Electrical question[FOG] Finally found and purchased my Kundig wide belt sander

 

开云体育

The Kundig is now safely in my shop.? As to wiring and breaker size, I am confused.

?

There are three different current specs in the manual and machine data plate.

  • The machine plate says 86A at 230V
  • The spec sheet says “connected load 130 amps at 230V”
  • “Required fuse 63 amps at 230V”?

The seller had an electrician wire it to his rotary phase converter and they used 2 gauge copper.? I think the manual said to use 6 AWG.

?

Questions:

  1. What size breaker should I order??
  2. What wire gauge should I run?
  3. There is a euro disconnect on the machine, does that meet US code?? The machine is about 30 feet from the breaker panel.
  4. There is about a bit more than 30 feet of 2 gauge wire that came connected to the machine.? I assume it’s ok per code to put a pull box and have a junction there so I can use the existing wire and just add to it to reach the panel?

?

On dust collection the spec sheet does not make much sense.? The machine has a 7” duct.? The spec sheet says 2700 cfm and 4500 fpm.? But when you do the math, with a 7” duct and 4500 fpm you get 1200 cfm.? Or for 2700 cfm you would need over 10,000 fpm.? Clearly wrong.? Prior owner had a 5HP Oneida with about 50 ft of duct and no issues.? My collector will pull 4500 fpm on a 7” duct? at the machine.

?

The machine plate says 86A at 230V

?

The spec sheet says “connected load 130 amps at 230V”? but it also says “Required fuse 63 amps at 230V”?

?

The motor is 25HP.? I do not yet have the machine in the shop so I don’t have the motor electrical data.? There is also a 1HP feed motor and a 1HP table height adjust motor.

?

Google says a typ current for 25HP motor is 74.8A.?

?

For experts, what size wire for 50 ft and what size breaker?

I decided a few years ago that when I got the large shop I would add a wide belt.? I also decided a wanted a constant line pass where the bed stays stationary and the head moves so infeed and outfeed tables can be fixed.? That narrowed the field considerably.? I ideally wanted a Kundig 37" or 43" single head with platten as a single head is all I can handle without increasing the dust collection beyond the 5HP Smart collector.? I see 2 head machines 43" machines but I've not found a single head in 3 years.? Well last week I found an add for a single head 43" Kundig Topic and only 32 miles from my house.? Pics to follow once moved and in place.?

The machine is in a workshop with a gravel driveway (rigger needs the right forklift) and at my shop we have 120 feet of pavers.? Estimate to pick up and deliver and place in shop is right at $1000.? Does this seem about right? I pay $185 an hour for the 2 guys and truck and plywood to protect the driveway.

If your 2 AWG wire that came with the machine is copper, then you can use a 100 amp circuit breaker with it.



If you want to run 6 AWG copper, then the circuit breaker should be 50 amp.? ?Since you already have the 2 AWG wire, I would go that route.

question 4 seems like a NO answer,? ?Just put the 100 amp circuit breaker in the panel and connect the 2 AWG wire to it.? ?Is the 2 AWG wire 2/2?? ?Meaning a white, black and bare wire in the group?

I don't know anything about Euro disconnects.? ?So question 3 is unanswered here.

The 2 gauge that came on the machine is three power conductors and lighter gauge ground wire.? Is a pull box as a junction with wire nuts inside to extend the wires that came on the machine ok per code?

So, your 2 gauge wire is 2/3, meaning three 2 gauge conductors (red,black,white) + 1 ground wire.? ?The circuit breaker would be double-pull 100 amp for up to 240v.

On the road so can’t send pics.? 25HP 3 phase machine.? Was wired at sellers shop with three 2 AWG copper conductors and a smaller gauge ground wire.? He had it wired to a knife switch was connected to a VFD.? I kept the wire he had from the sander the knife switch, about 30 ft.? I would like to use that wire but I need 40-45 ft to my breaker panel to go up to the ceiling, across and down.? The wire will run in steel conduit.? I am assuming I can have a junction box to extend the existing 30 ft of wire to reach my breaker panel.

?

Questions:

  1. I think you need a disconnect for the machine.? Does the factory Kundig euro rotary disconnect meet the code requirement or must I add disconnect near the machine?
  2. Any issue with a junction box to extend the wire?

I decided a few years ago that when I got the large shop I would add a wide belt.? I also decided a wanted a constant line pass where the bed stays stationary and the head moves so infeed and outfeed tables can be fixed.? That narrowed the field considerably.? I ideally wanted a Kundig 37" or 43" single head with platten as a single head is all I can handle without increasing the dust collection beyond the 5HP Smart collector.? I see 2 head machines 43" machines but I've not found a single head in 3 years.? Well last week I found an add for a single head 43" Kundig Topic and only 32 miles from my house.? Pics to follow once moved and in place.?

The machine is in a workshop with a gravel driveway (rigger needs the right forklift) and at my shop we have 120 feet of pavers.? Estimate to pick up and deliver and place in shop is right at $1000.? Does this seem about right? I pay $185 an hour for the 2 guys and truck and plywood to protect the driveway.

On the road so can’t send pics.? 25HP 3 phase machine.? Was wired at sellers shop with three 2 AWG copper conductors and a smaller gauge ground wire.? He had it wired to a knife switch was connected to a VFD.? I kept the wire he had from the sander the knife switch, about 30 ft.? I would like to use that wire but I need 40-45 ft to my breaker panel to go up to the ceiling, across and down.? The wire will run in steel conduit.? I am assuming I can have a junction box to extend the existing 30 ft of wire to reach my breaker panel.

Questions:

  1. I think you need a disconnect for the machine.? Does the factory Kundig euro rotary disconnect meet the code requirement or must I add disconnect near the machine?
  2. Any issue with a junction box to extend the wire?

If your 2 AWG wire that came with the machine is copper, then you can use a 100 amp circuit breaker with it.

?

?

If you want to run 6 AWG copper, then the circuit breaker should be 50 amp.? ?Since you already have the 2 AWG wire, I would go that route.

question 4 seems like a NO answer,? ?Just put the 100 amp circuit breaker in the panel and connect the 2 AWG wire to it.? ?Is the 2 AWG wire 2/2?? ?Meaning a white, black and bare wire in the group?

The Kundig is now safely in my shop.? As to wiring and breaker size, I am confused.

?

There are three different current specs in the manual and machine data plate.

  • The machine plate says 86A at 230V
  • The spec sheet says “connected load 130 amps at 230V”
  • “Required fuse 63 amps at 230V”?

The seller had an electrician wire it to his rotary phase converter and they used 2 gauge copper.? I think the manual said to use 6 AWG.

?

Questions:

  1. What size breaker should I order??
  2. What wire gauge should I run?
  3. There is a euro disconnect on the machine, does that meet US code?? The machine is about 30 feet from the breaker panel.
  4. There is about a bit more than 30 feet of 2 gauge wire that came connected to the machine.? I assume it’s ok per code to put a pull box and have a junction there so I can use the existing wire and just add to it to reach the panel?

On dust collection the spec sheet does not make much sense.? The machine has a 7” duct.? The spec sheet says 2700 cfm and 4500 fpm.? But when you do the math, with a 7” duct and 4500 fpm you get 1200 cfm.? Or for 2700 cfm you would need over 10,000 fpm.? Clearly wrong.? Prior owner had a 5HP Oneida with about 50 ft of duct and no issues.? My collector will pull 4500 fpm on a 7” duct? at the machine.

?

The machine plate says 86A at 230V

?

The spec sheet says “connected load 130 amps at 230V”? but it also says “Required fuse 63 amps at 230V”?

?

The motor is 25HP.? I do not yet have the machine in the shop so I don’t have the motor electrical data.? There is also a 1HP feed motor and a 1HP table height adjust motor.

?

Google says a typ current for 25HP motor is 74.8A.?

For experts, what size wire for 50 ft and what size breaker?

The Kundig Manual is not super helpful.? The seller gave me three copies on the manual and all three have different specs for electrical.? One is in a college theme paper binder and it seems to have the most complete specs but it too is confusing.

?

  • “Connected load” = 130A at 230V? (connected load is supposed to be the FLA for all motors).? The machine has a 25HP main motor, 1HP feed motor and 1HP height adjust motor.? Does not seem like these three could get to 130A.
  • “Required Fuse” = 63A
  • “Power Cable Size = 6 AWG

?

I have not looked at the motor plate on the 25HP machine but google says 25HP motors @ 230V draw 68A.? Plus the feed motor.? Seems odd that Kundig would spec 6AWG which has a max of around 65A.

?

The original owner had a licensed electrician wire his machine and they wired it with 2 AWG wire which looks like it was sized for 130A as that’s the max spec for 2 AWG copper.?

?

There was about 35 feet of 2 AWG copper already wired to the machine.? So I decided to extend that with 2AWG and I used a 100A breaker which I found in one guide as the right size for a 25HP 230V 3 phase motor.

?

The dust collection specs make no sense either.? The machine has a 7” port and the manual says it needs 2700 cfm and an air speed of 4500 ft per min.? The mechanical engineer in me wanted to dig into that.? The math is pretty simple.? With a port there is direct relationship between CFM and velocity.? For a 7” port:

  • 4500 ft per min velocity equates to 4810.56 cu ft/ min
  • 2700 cu ft/min equates to 2525.69 ft per min velocity

Joe, your CFM calcs are mistaken.

> For a 7” port:?4500 ft per min velocity equates to 4810.56 cu ft/ min

7" diameter has area of pi*3.5^2 = 38.5 square inches, divided by 144 = .267 square feet.

0.267 sq ft * 4500 feet/minute velocity == 1,200 CFM

Agreed, manual specs don't make sense.? ??

I don't know know anything wide belts specifically, but 25HP is a lot of material removal power, and crude extrapolation from saws suggests to me that 4500 fpm and 1200 cfm is nowhere near enough to pull 25HP worth of dust.? ?

I would note that the spec of 2700 cfm @4500 fpm is very close to two 7" ducts could handle.? Is there any chance there's two ports?

As one random point of comparison, I glanced at specs for a 25HP grizzly WB and it has six 4" ports, which is close to area of two 7" ducts.

Presumably Kundig can help clarify.?

The Kundig has only one 7” port.? Seller had a 5HP Oneida with about 50 ft of duct and in the test before buy dust removal was great. Machine was really clean inside too, and not blown out, I could tell.? I have the same collector and less duct.? I looked a lot at dust collection before buying as in my setup it would be a challenge to put in a bigger collector.? I saw a lot of Kundig two head machines.

Joe, are you running a Smart Collector on the Kundig?? The extra pull under pressure should be a real benefit.? Sanding either wide, or thick pieces are always the problem with a WB.? Too little or too much make up air.? I find that thick pieces are the bigger issue as the distance from the table to the dust port is greater and the air entering around the stock is more than the DC can pull out.? In those cases a 37" should be much more efficient than my 43" so I'll bet that one 7" port with your smart will be fine most of the time.? How much gets to the filters and how often you need to clean them will be interesting.? Let us know how it works.? Dave

I don't know know anything wide belts specifically, but 25HP is a lot of material removal power, and crude extrapolation from saws suggests to me that 4500 fpm and 1200 cfm is nowhere near enough to pull 25HP worth of dust.? ?

I would note that the spec of 2700 cfm @4500 fpm is very close to two 7" ducts could handle.? Is there any chance there's two ports?

As one random point of comparison, I glanced at specs for a 25HP grizzly WB and it has six 4" ports, which is close to area of two 7" ducts.

Presumably Kundig can help clarify.?

I am using the smart collector. Will report once I’m running.

Has anyone had a drum recovered? There is deep damage on one end about 2” wide. I knew this when buying.

Joe, are you running a Smart Collector on the Kundig?? The extra pull under pressure should be a real benefit.? Sanding either wide, or thick pieces are always the problem with a WB.? Too little or too much make up air.? I find that thick pieces are the bigger issue as the distance from the table to the dust port is greater and the air entering around the stock is more than the DC can pull out.? In those cases a 37" should be much more efficient than my 43" so I'll bet that one 7" port with your smart will be fine most of the time.? How much gets to the filters and how often you need to clean them will be interesting.? Let us know how it works.? Dave

The CFM in the Kundig manual makes me wonder if the manual was written for a two head with two ports and not edited for the single head machine.? My 43" two head has two 180mm ports.? Dave

I've found Chris Peterson to be a good source for WB repair info.? You can email him - comprehensiverepair.com.

Hi Joe,?
I recovered a 24" WB roller many years ago- used Finzer roller in Des Plaines IL. Easy and was only a couple hundred dollars

I don't recall it being a nightmare?but it was heavier than I expected because it was solid.?? It was an old Timesaver with that great logo of the man pulling the hands of a clock backwards.?
