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

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?

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.

?

The pull-box sounds like your connection for the machine.? ?Need pictures.

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?

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 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?

?

That is big ¨C what are the amps and the dust collection requirements?? Sorry if I missed this -

I think the price is about right considering that nothing gets done cheap with people in short supply.? Kundig are sweet so I hope it works well for you.? I'm guessing 2000- 2500 lbs?? Dave

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.
