I get asked ALL THE TIME.. can I plug my 240V brewing system into my dryer outlet? I decided to make a video showing how to make a power cord with inline GFI protection so you can. It is about $100 for all the parts. Only limitation is it is only able to handle 4800 watts max (20 amps)

Thanks for the video. I recently put a GFCI breaker in my dryer circuit rather than go this route. It was only about $80 for the breaker, and the 30 amp inline GFCI cords were much more expensive.
Breaker in the main panel is definitely better way to go. HOWEVER.. those in apartments and rental that can't change breakers will get good use of this cord. :yes:

Thanks for the video. I was thinking I'd be stuck in 120V land for some time (rental), but this made me look at the foundry as it can switch between 120/240 if the proper power source is available. Great for taking the rig to a friends house with 120V but still able to use a dryer 240V at home!

So what about something like this?
inline GFCI
plus
extension cord

Both components look like they're rated at 30A (7200W?) with 10awg. The combined cost is significantly cheaper than installation of a new outlet in my garage. I don't rent, but I do move every 3-4 years so I've been looking for a portable solution.

It doesn't look like the two items have compatible plugs.
Maybe I'm overlooking something simple...I'm very new to electric brewing and the terminology. Here's how I read it:

Dryer outlet = 14-30R (female)
Inline GFCI = 14-30P (male) to 14-30R (female)
Extension cord = 14-30P (male) to 14-30R (female)
Brewing system cord = 14-30P (male)

Are there subtleties to the plugs that I'm not seeing? Is it the twist lock thing?

Yeah the extension cord is twist lock and the gfci pigtail is straight blade. It could be changed on the pigtail but that is a little work.

I see, thank you. I found this and the corresponding 14-30P to L14-30R adapter but I'm now quickly getting into frankenstein territory with all the connections, and the total cost is pushing $500. May be worth it just to have the electrician wire it up.

So my electrician just quoted me $1100 to wire up the sub panel. :no:

I get that my Frankenstein solution isn't pretty (outlet, pigtail, adapter, extension cord, adapter, kettle)...but is it safe?

You likely already know the answer to that question by virtue of asking right? I’m not an electrician (nor can I even pretend to be one, electrical work scares the 💩 out of me) so I’m not qualified to answer in any fashion.

But..a sub panel is bound to have future use case of some sort right? Doesn’t seem like a bad investment to make if you think of it that way?

I don't actually...it's an honest question. It seems safe to me, if not a little unorthodox, but I know next to nothing about electricity.

As for the future use case, it actually tilts toward the portable solution. I'm guaranteed to move in 3-5 years, so any money I spend on permanent wiring is sunk cost.

$1100 sounds really high.

A spa panel costa about $80 in my area. To wire in a 30amp plug about 2 feet away from my main panel in the garage cost about $170. I would get a second or third quote.
