4800w, I gotta install a 30amp breaker and run the line to the garage...

What kinda wire do I need? Would armoured 10-3 be the ticket here? I assume home depot would be a ripoff for wiring... How much should this stuff cost per foot? I likely only need 20-30'
 
For residential you dont need to use bx you can use romex.

Does this heater require a neutral? If not you only need 10/2.

Your likely not going to find a better price than depot.
 
BX is good if you are going to do any surface mounting. Use 2 conductor. Don't waste money on 3.

Should cost around $1.50 a meter for 10/2 AC90.


Edit: At the depot, likely cost closer to $2 a meter.
 
I'm not sure actually... It has a 3 prong plug if that means anything?
 
I figured bx would be nicer because it will be exposed. What's the price diff?
 
Didn't buy yet but yeah that will be the one.

OK so I'll go with 10-2 BX

Thanks guys
 
I just did this exact install

romex 10/2. Use a double pole 30 amp breaker to distribute the load. Hopefully you have GE breakers. Double pole 30 is $30. Others can be up to $90

The romex was $2 a foot Or there abouts I believe

Will you ever use a 220v welder or anything else in there? It's worth the time and money to install a switch box and a plug.

Switchbox to turn off the power, plug, to allow for different implements

just a thought
 
AC(BX) cables always contain a bare "grounding" conductor, but it isn't counted in it's naming. 10-3 has four conductors, two insulated one bare "ground".
Your plug has two phases and a "ground".
AC90 12/2 is good for 30A.

Click to expand...

Unless you own a panel box where they don't make the breakers for anymore.... anybody who pays $90 for a 30 amp breaker is insane.

Even $30 is kinda highish.

I dunno about your garage, but my garage was woefully underpowered originally.

Running a compressor and ANYTHING else would trip the 15 amp breaker.

I ran a 10/3 wire with 30 amp breaker and added a large receptacle with one of the receptacles being 240V,

Now i can run my mill, lathe, compressor, flood lights and still be good!
