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

yes that would be perfect. I would just need to change out the cord for my dryer to something longer. So I need to do some research to make sure the cord connecting from the box in the picture to the single 240v was proper gauge or larger.

You may be getting ahead of yourself. I’ve read several posts on other forums that Griz is out of 8” jointers (all of them, I guess) for a while. Hope that’s not the case and you get one, but you might want to check on delivery first. That said, the 2 outlet box whyme suggested would be a good solution, though I suspect you’ll have a 20 amp outlet for the jointer and a 30 amp for the dryer.

- BlasterStumps

The Makita 2040 is rated at [email protected], so a 20A circuit is more than enough for it (A dedicated 15A one would work as well). But it’s also a brushed universal screamer motor, so a different animal than the machine in question. The Grizzly has an induction motor, which will have an FLA of around [email protected] give or take a few amps. A 30A dryer circuit will be more than sufficient, and a 20 foot extension cord is easy to make.

Cheers,
Brad

PS: Instead of making an extension cord for my 3hp table saw, I just put a 25 foot cord on it. I do have an extension cord for it as well, but it was originally made so I could move my welder (a MM210) out into the driveway. Rarely use the extension cord, but it’s nice to have if needed.

I’m not at my computer at the moment, so I can’t easily look it up, but my gut says that you’ll need a 10 gauge extension cord for a 30-40 foot run. Look into the kinds of things stage lighting people use (stranded 10 AWG 240V).

If the jointer uses a 20A plug the safest way is to use a 2 space main lug panel with a 30A breaker for the dryer and a 20A breaker for the jointer. So you’ll have the 30A dryer outlet feeding the panel and the panel will have a 30A cord and outlet and a 20A cord and outlet. You could hang the panel on the wall by the dryer if you have room. This way is obviously more expensive but a safer setup..

Panel like this… http://www.homedepot.com/p/Murray-60-Amp-2-Space-4-Circuit-Main-Lug-Surface-Mount-Load-Center-LC002GS/202253181?cm_mmc=Shopping%7cTHD%7cG%7c0%7cG-BASE-PLA-D27E-Electrical%7c&gclid=CIzF3u7yytMCFcaPswodfakCSQ&gclsrc=aw.ds

WhyMe what is the box you pictured above? what is it called and I am assuming it can be bought at home depot or lowes?

The outlet box pictured is most likely home made. I was suggesting to use the main lug panel plugged into the dryer outlet, not as a permanent install. It would be similar to the outlet box but you’d have the benefit of the breakers.

Sadly, the unplug and plug thing seems to be the “gotta do it.” I haven’t ran the extra lines yet and have to do this between my heater, the jointer and the table saw. Sucks, but it just is.
