I am looking at getting an 8” grizzly jointer and the one I think I am settling on is single phase 240v… the bad thing is I live in military housing and cannot change circuits and the only 240v is the dryer… The dryer is the room connected to the garage.

Is there any way to have two 240v connections going to that same plug. So I can easily switch between using the dryer and using the jointer. Also is it feasible to have a 20-30ft long 240v cable extension going from the outlet to the jointer plug?

I know none of you are electricians ( some of you may be ) but i just want to know if this is all in the realm of possibility.

Actually there are quite a few electricians on here bud :)

Yes to a cord. Sized properly it can be as long as you want.

No to 2 connections. Can’t run them at the same time.

i realize i couldn’t run them at the same time but for ease of use would a pigtail to the 240V outlet work. then one plug for the dryer and then the “extension” for the Jointer out to the garage. Keep the dryer off when i run the jointer and the jointer i would probably leave unplugged in the garage when not in use.

Not the way to do it. You’d have to unplug and plug as needed.

alright i appreciate it Fridge. kinda sucks since moving a dryer to plug in a jointer can be a pain. any tips? to make it more accessible?

If it’s behind the dryer I’d probably make a small cord to make the dryer plug more accessible


Whats the motor size? I d see if it could be switched over to 120V. May not be as efficient but you could possibly get by that way.

true as well

sorry for the other post. thinking more about it, the motor will most likely take a 30 amp circuit to run it. If you have a 30 amp circuit in the garage, then I would think maybe switching it over might work.

Fridge, yes the plug for the 240v outlet is behind the dryer.

I mention the possibility of it being 30 amp, but that is only a guess. take a look at the nameplate.

I run a Makita 2040 planer on 120V 20 amp circuit. It’s a little weak but it works if I don’t make it hog in cutting.

I would guess just about 30 amps full load. I think they have a 3-hp motor. Nice jointer by the way.

As long as you use the proper sized cord it will be fine to create a box with the 2 sockets needed for the dryer and jointer. I would make the cord long enough to get the sockets out from behind the dryer. Something like this. The jointer should not need a neutral.

might be a grounded 6-20 plug on the jointer
