« Part 3: Putting the tape on my saw? Part 4 of Getting my tools ready series Part 5: Outfeed table with router? »

I will have to put new wiring in for my 220 single phase 1023sl grizzly bear. Thats the next step so I can make hardwood rails for my “too short ” dollies.

I have GFI’s in line on all 110 circuits. It appears that I can only get a 220 GFI cuircut breaker?

Will be going to my second home..My favorite “Box Store” to pick up some electrical hardware.

Will I have to mount a 220 single phase gfi in the panel?

Should fit in the place of a normal breaker. Not sure you need one for that though. If you haven’t already, check the code.

I used 220 GFCIs for the general outlets my shop because I used Edison (shared neutral) circuits, and you can’t do that with sockets. Dayumn those suckers were pricey. And I had to special-order them.

However, I believe that code says that if you only have a single dedicated outlet you don’t need a GFCI. This is for things like freezers and other single-purpose appliances (where nuisance trips could be hugely expensive), but it suggests that you should be able to get away with a standard 220 breaker. Check with your local building department, but I’d just go with a single outlet and a regular breaker.

I have a call in. Have a permit that I have to keep renewing because I asked for an inspection after the electricial broughtthe wiring to the shop.. He and I finished the outlets. The inspector wanted some things done differently, and that was a couple of years ago. Grizzly manual for the old bear suggests a dedicated 20 amp. But that was a awhile ago.

The COST of ground faults for the 110 are about 6 for one GFI 220! Don’t want to have to redo it?

Gizzman! I’m a pretty good carpenter/contactor/electrician. I have lots of information/ but my experience at fine woodworking is minimal. Lots of practice on prototypes?

LittlePaw, if it doesn’t work the first time…that’s normal! LOL!

Something dose not make since Doc.
I have 220 circuits in my shop and none are Ground Fault. I bought a 20 Amp & 30 Amp breaker a couple weeks ago and they were not G F. Take another look in the Big Box Store. The only thing of is where you live they have a special Code for out buildings. All my 110 Volt circuits are G F protected.
