I guess they are also putting an emphasis on pulling permits for indoor grow rooms. Law has always been there just now being enforced. Dont tell them its for a grow room if you dont want the permit pulled. Some guys on craigslist are pretty cool and if you pay cash with no receipt they hook you up and do it to code without pulling a permit, thats what I heard anyways.
Did you mean 'convoluted'? Anywho...I'm a licensed residential/commercial/industrial electrician myself, and anything I've said in this thread is what I would either do at my own home or a customer's home lol...and would also be to code.
ever get hit by a service line?...it's high enough to kill you...but you're gonna say you can die from 110 and all this nonsense ...I been hit, like all electricians with 110... only once from 220 and could taste the filling in my mouth ...had a lock out tag on the panel carpenter decided it's ok....BUT The term high voltage usually means electrical energy at voltages high enough to inflict harm on living organisms. Equipment and conductors that carry high voltage warrant particular safety requirements and procedures....not what you think is high voltage but you knew that..
i am an electrician, and from reading the op's posts, i would recommend outsourcing and finding a residential helper or journeyman, or an actual electrician to see it done safely. no one mentioned a multi tap ballast, and that's a thing to consider when running 10/2 or 12/2 and whether you're running 240v at half the amps or 120v at twice.
your post was relevant, and i agreed with most of it so i quoted you. this isn't a bad thing buddy, i promise. you and that other guy got pissy with each other, with no true solution reached.
a lot of people use recep/device ratings, not knowing that it isn't 110vac and 220vac, but actually 120vac and 240vac.
agreed, it's easy to kill yourself, and not much harder to hire a professional. if he gets zapped, it's on him. if your home burns down, he's liable.
What I'm saying is that, at least in North America, there is no single conductor carrying 240V. In North America 240v or 220v whatever you want to call it is just two 120 legs combined...so to get hit by 220 one would have to somehow encounter both legs simultaneously, which would be hard to do not on purpose.a lot of people use recep/device ratings, not knowing that it isn't 110vac and 220vac, but actually 120vac and 240vac.
i saw that too
Yeah not two weeks ago, we were called out to do a demo/rewire on a trailer that overloaded its service...tenant told land lord that he had to plug in heaters for his fish tanks lol, then suddenly disappeared and never came back to get his 'fish tank eqpt' haha. Probably the easiest way to get busted if you're not a seller.
true, hence the double pole. but if you cut a live 10/3 or 12/3, you're gonna get hit by both sin waves, simultaneously. however, the amps are halved, so the bite is more a pop than a grabshitanddieohfuck... burns or blasted holes are more common when shorting a double phase line than single phase 120v.
i own exotic reptiles, they use MUCH more power than the 4kw used in the grow room. the fish thing isn't a stretch, but a guy needing shit for a bunch of water tanks in a trailer? um... fishy? i'd never put more weight on a trailer floor than a single 55g fish tank. that shit will fall straight through the melamine...
If you F up on 240 v then you buy the farm. Just like Mel did.
