>buy 7500w 220v heater for garage>internet says use 8/2 wireI went to the store and the 8/2 wire was 3 wires. Isn't 220v 4 wires? Asking because I cannot into Google I guess and don't want to buy the wrong expensive shit, run it through the wall, then have the electrician connecting it all show up saying nope.
if you're hiring an electrician anyway why the fuck are you buying the wire
>>28688382I'm not going to pay someone 500 bucks to snake a wire 30'.
>>28688383it will cost that much and more to undo your inevitable fuckup
>>28688377kekhope he billed ur dumb ass a 3hr min
>>28688385I'm just asking about wire type, homie. I need no opinion on the project itself.
>>28688377This isn't the right board, try /diy/
>>28688390>I'm just asking about wire type, homie.If you can't determine requirements for a three or four wire routing for 220V, you're not up to the task to do your own electrical work, especially high voltage electrical work.>I need no opinion on the project itself.Anon >>28688385 basically predicted your future with near certain accuracy. Just pay the electric pixie man the money to do it right.
>>28688377this is /o/ not /diy/
>>28688390>Idk about electrical Then ask the electrician
>>286883778/2 is two wires for the load and one for grounding. 8/2 should be ok for your heater but i would recommend moving up to 6/2 so when you inevitably buy a EV you can charge it on the same wire. 220v can be 2 or 3 wires + a ground depending on if the appliance needs a neutral. if you could use google to figure out wire size vs. length but cant use it to figure out the rest of this simple project, you should just call a electrician its probably a $1500 job
>>28688377>Isn't 220v 4 wires?Assuming you're in the US and you mean 240V, you get this by running two phases from your load center to the receptical, and a ground wire, so no, it wouldn't be. The voltage difference between the two phases would be 240Veveryone else in this thread is a retarded pussy
>>28688377You shouldnt be listening to "the internet" for wiring your heater.What did the instructions say?It did come with instructions, didnt it?
just shoot from the hiprun those cableswhat's the worst that could happen
>>28688377nigger still hasn't posted what model of heater he has. Great bait
>>28688377>Isn't 220v 4 wires?No. That's why old dryers are 3 wire. The 4th in a 220v is the ground wire. Old 3 wires ran 2 hots and a neutral.
>>>/diy/fuck yo house nigga we racing cars
>>28688377>7500w 220vYou can't get that much wattage out of 220vYou're getting like 3000w
>>28688390>>28688383electrical is one thing you do not fuck with if you don't know what you're doing.you WILL burn your fucking house down.also >>>/diy/they know a lot more about electrical than /o/. I have a 220 outlet but I had my electrician friend install it for a case of beer because I don't know shit about that and know high voltage is scary.
>>28691045It's 240v... 240v at 60 amps is 14.4kw. A 30A breaker will do 7.2kw.
>>28691069as a red blooded american, I still don't know if I have 220 or 240 in my garage. It's a 50 amp breaker for a welder I think it's 240?
>>28689220LOL
>>28691080It's 240Vpeak, 208Vrms in your garage. You can have a 50 amp breaker regardless of voltage. It's a matter of sizing the right cable to carry just over that 50 amps.
>>28691164Actually this depends on what you have at your electircal service entranceIf your 120 Vrms service is made from center-tapping a secondary winding, then you have 240 Vrms between each phaseIf your 120 Vrms service is made between neutral and either of two phases from a three phase system and, then there is 208 Vrms between those two phasesOP if you're the only one in your house then just go ahead and do the wiring yourself with a 8/2, put each one of the power conductors on a different live phase, take the risk and learn somethingIf you have children or parents in the house then ask on electrician
