I don't do enough welding to justify a 220v welder. And the welding I am going to do is body panels so the 135A will be perfectly fine.You might consider a 50a wall plug for the heater. That way, should you choose to do so you could upgrade to a 220V welder. Unplug the heater when wanting to use the welder. My 211 is multi voltage, but I hate running it on 110.
Lol thanks sir. I was thinking of 8ga as a min, my Dad currently has it wired with 10ga but had a smaller heater in its place before.Because a 50 amp heater will be run continuously it should be wired with 8 Gauge as a minimum.
Any technical information you take from me is guaranteed to be worth exactly what you have paid me for it.
How in the world did you come up with that? This isn't an intermittent use device like a welder.I don’t know why 10 gauge wouldn’t be good nuf. Heat in your garage will be a wonderful thing so best of luck.
how can you come up with that when you didnt have the wattage rating of the heater?kinda depends how far the plug is from the service panel, but i'd think 10 gauge should be ok if it's within 20 feet. disclaimer i'm not an electrician so if anybody has good information to post why 10 isn't stout enough I'm all ears.
you will need 52a rated wireIt is a 50a single phase 10,000w 240v heater that is going to be hung from the ceiling, the heater is currently hardwired in my dad's garage. it's going in my garage, I live in Michigan it snows 3-4mo/yr. I stated in my first post, it will be hardwired. The heater has an integrated on/of switch with a wireless remote.
you clearly dont know how to calculate required wire sizes for circuitsI don’t know why 10 gauge wouldn’t be good nuf. Heat in your garage will be a wonderful thing so best of luck.
technically #8 THHN is too small since its rated for 50a...Because a 50 amp heater will be run continuously it should be wired with 8 Gauge as a minimum.

you should use #6 NM-b or THHNLol thanks sir. I was thinking of 8ga as a min, my Dad currently has it wired with 10ga but had a smaller heater in its place before.
no it absolutely wont work at all. i posted the math above.This is how I learn instead of googling everything.
So granted 6 would be awesome snd 8 would be ok but are you guys saying 10 won’t work?
It would work in that the heater would turn on. It would even run until the wire overheatedThis is how I learn instead of googling everything.

Its not really a 52 amp continuous load. Its a 41.6 amp load ( 10,000/240= 41.6amps) But being a circuit for a heater, it is classified as a continuous load. So you multiply 41.6 x 125% = 52 amps. That is what you size your wire and OCPD off of. The heater is not going to draw more amps the longer it runs, it still will draw 41.6 amps. But the longer the heater runs, the wire will heat up for longer periods. That is why it is over sizedI stand corrected, a 52 Amp continuous load is too much for 50 Amp wire.
Better go with the #6 and be safe.
IMHO, a wire rated for 41.6 amps won't overheat at 41.6 amps (note, you still need #6 wire). It's that "most" breakers are only rated for 80% continuous load. They won't flip immediately, but they'll flip within 2 hours or so give or take.But the longer the heater runs, the wire will heat up for longer periods. That is why it is over sized
Where are you getting your info from that breakers are only rated at 80%? That's misinformation. The 80% is a NEC rule. Breakers are designed to handle 100% of the the listed amps.IMHO, a wire rated for 41.6 amps won't overheat at 41.6 amps (note, you still need #6 wire). It's that "most" breakers are only rated for 80% continuous load. They won't flip immediately, but they'll flip within 2 hours or so give or take.
The point I was trying to make is that this is a 41.6 continuous load, not a 52 amp continuous load. The 52 amps is the sum after doing the math for a continuous load, and this is what we size the conductor off of.IMHO, a wire rated for 41.6 amps won't overheat at 41.6 amps (note, you still need #6 wire).
