Comfort Zone 7500w garage heater

[Smokesmore]

Hello all, I'm not sure if this is the right forum but I will share what I have. I'm going to be installing a heater in my garage (see title) My plan is to run some 8/2 wire from the electrical panel in my basement through the floor boards and into my garage. I will install a disconnect box just below heater in garage and then use some flex conduit to run the wire to the back of the heater.

It looks like the heater pulls about 32.5 amps running on its highest setting so I'm thinking a 40 amp breaker for my panel should be sufficient.

Does everything sound like I'm setting this up right? Am I missing something?

what is 8/2 wire? are you outside the UK?

 

[davesparks]

I'm going to hazard a guess from the terminology that you are in the USA?
If so you'll probably be better off with a USA based forum, the vast majority of the membership of this forum is UK based.

8/2 is 2 core 8AWG wire I think.

 

[Smokesmore]

Oops... yeah I'm in the US. Didn't notice this was a UK forum. Yes 8/2 is 8AWG. Sorry about thay.

 

[ayjay]

isn.t the usa 110v?

 

[telectrix]

it's both 110 and 220. the 220 being derived from 2 phases ( i think).

 

[Smokesmore]

Yeah we are 110v. 8/2 wire is just 8AWG with a positive, negative and ground.

 

[telectrix]

@110V your current would be 68A though.

 

[davesparks]

They use the 220V between phases for higher current loads normally though.

 

[telectrix]

yeah, OK if using 2 phases to get 220V.

8AWG is way too small. You need 6.

Look at 210-3 and 310-15 in the NEC or hire a local electrician that knows the codes for your location

Well that's amazing, if this guy is American even more so if he works within the electrical industry, because the standard nominal voltage for domestic supplies throughout the USA is the 3 wire single phase 120/240V . 110V hasn't been seen as a public supply voltage in the States for at least a couple or more decades now!!!
