Are those whole house units still only one use ?


One use? ? You mean like a fuse? ? No. ?They come with some kind of warranty but likely last forever. ? Link below is to a brand sold at Home Depot. ?It is the plug-in kind and only works with their brand. ? ?Every brand has these and installation is trivial if you have space in the panel. ?Oh, notice the “replace” light. ? I guess it is concievable it might go on after just one direct hit by lightening but more likey it will live in the panel for 30 or 50 years.

The OTHER thing that is now required is “combined GFCI arc-fault breakers". ? People hate them because of nuisance trips. ?They cost $100 each and you might need a couple dozen of them. if you are putting in a pen panel. ?They add $1,000 to a typical job. ? But there is no possible way to ever have an electrical fire or electrocution. ?So they are worth the added $1K.

As long as we are at it. ?In Calif. all new contruction must have solar panels on the roof.

The “best”? ?The latest electric code (here in the US, the NEC) has taken all the fun out of this. ?All new service entrance panels are required to have “Whole House” surge protection. ?This only applies to newly installed panels in new construction or retrofit. ?But if you are going to worry about protecting stuff, you might as well just do it once

These devices are easy to install into an old panel and because they are required, they are available “everywhere”. ? ?Just put one of these in and be done with it and it will cover your TV, computer, power tools, car charger, and whatever.

There are two basic kinds, one snaps in like a larger size 220 volt circuit breaker and the other screws into a knockout.

OK, but you really wanted a AC-DC-AC system. ?You might be in luck because that is how all brushless motors work. ? There is one of those inside the lathe already if you have a brushless motor

But if I am not mistaken, I think all mini lathes use PWM to control the motor. ?If so, then you already have a kind of AC-DC-AC system in from of the lathe's motor.

What is the best AC protector/stabilator for a 7x14 lathe?
There are many types: one for your computer, one for your fridge.
Full AC-DC-AC is maybe a littlebit luxury?
