how to wire 220 basement outlets + protection

[Curious Hound]

OT;
All my 5hp motors pull 22-25 amps. Its what I look for in amperage when I look at a "5hp" motor on compressors because of manufacturer inflation.
So why is a 2hp motor pulling the same? Is it less efficient motor?

He said his is rated 12amps.

 

[Curious Hound]

1500 watts is about 12.5 amps at 120 volts on bob math.

That's good math.

And 1hp is 746watts. 750 is a great number for estimating.

He said his is rated 12amps.

"same size motor, 2hp, on 120volts would pull 24amps."
This is what I was referring to...

Sorry. I didn't follow your train of thought there. It may be a different type of motor with a different efficiency. I'm not sure. I just looked at my air compressor. The motor itself doesn't list hp. But on the tank, the label says 3.6 hp. It's running on 240v and motor nameplate lists15amps. Some lathes do use different types of motors. I know for small lathes there is an actual type called a "lathe motor". Big ones usually run standard 3 phase power.

Or maybe maple syrup lubricates them better and drops the current.

I love maple syrup, but, alas that's way too much sugar for me. ( nah, couldn't be the tariffs )

reviewing the specs, nominal 8.9 amps, full load 12.9
I'll stick with the 15 breaker & receptacle but go heavy-duty on the wire. the run will be less than 15 feet.
already have a dedicated 220 for the mill, and of course the clothes dryer has it's own run. and the AC.

I'll look into dual GFCI breakers. the main panel is probably 50 years old,,,,,,?

Full load amps is what is used for designing the circuit and overcurrent protection.

"I'll look into dual GFCI breakers. the main panel is probably 50 years old,,,,,,?"

Yeah. That could be an issue. Just use your common sense and don't touch any live wires while you're soaked in saltwater.

so you're saying don't work so hard to get all hot 'n sweaty then lean on the adjacent steel bench?

 

[pjtoledo]

getting interesting.
panel is Federal Pacific stab-loc, takes breaker types NA, NC, NAGF. it was probably 10+ years old when we bought this place in 1985.
these are thin 1/2" breakers, doubles are 1"

I found Connecticut Electric UB1F0215N that is a 2 pole 15 amp, NC215 equivalent, non-GFCI.
the only GFCI breakers are single pole double width. not sure if I can tie-bar them together, or if that is a good/bad idea.

haven't yet found any 220 volt GFCI receptacles.

I wouldn't worry about gfci breakers for that. If you plan on living thete a long time, save up and get the panel replaced. Federal Pacific has a bad reputation and I have personalky seen some of the reasons why.

 

[Jazzer]

My sister’s townhouse burned down due to faulty Federal Pacific breakers. They were known in the trade as “no-blow” breakers. I’d definitely replace that panel.

 

[lil_Blue_Ford]

Yeah, Federal Pacific has a well-earned bad rep, especially the “stab-lock” breaker panels. I’d be thinking seriously about upgrading that.

I wouldn’t worry about a GFCI for what you’re doing.

I do agree that although 14 gauge is acceptable, 12 gauge is better. I do very little wiring in 14 gauge and usually most of that is when I’m working on older electrical or existing 14 gauge. Any new circuits I run are typically 12 gauge or larger (as needed).

15 amp breaker is correct for your application.

I put a 50 amp 220 plug in my parents garage because that’s what my one welder calls for. There’s a few other 220v tools that get plugged in there from time to time that don’t require a 50 amp breaker, but I’m not running another plug because nothing is a regular user of that outlet, it’s only an as-needed thing.

I looked at what I did for my air compressor yesterday, turns out I went way overkill with 10 gauge wire on a 15 amp breaker... don't remember why I went that big but I just bought the shortest spool they had and put an outlet where it fit... it's temporary until I get my shed wired and use the big compressor so I made it somewhat janky for routing.

 

[bobbywalter]

i would definitely in the data given with federal pacific developmewnt... line swap over a 60 amp sub panel with mo bettuh stuff...
