Cool, congratulations.
It has been said before that it was the war and it's copper restrictions that was the reason for the 3 wire feeds to ranges and dryers.
So can I ask if the 1943 allows ranges and dryers to be grounded via the neutral?
And do you have an earlier NEC?

Never heard of that before. The '43 is just a supplement, 49 pages, to the 1940. There were supplements in '42, '43, and '45. Then everyone rejoiced when they bought a brand-spanking new '47 after the paper rations were lifted.
But I'll do some digging into the 3-wire thing.

But I found this today, in my newly-acquired 1943 NEC:
So there it is, right from 'the horse's mouth'.
That does not make it a quality job just a legal one.If your working under me get use to pigtails fast.

I pigtail no matter what. And I abhor those who don't. I just posted this to 'set the record straight'.
Personally, I would really like to know the true cross-sectional area (cmil) of those little tabs you break off on a receptacle. Is it anywhere near even a 14AWG?

I seen a fire start over using them screws to feed thru.By luck i just happened to be there and quickly killed breakers and put flame out with water.Was an all wood cheeky hut.Rewired the place the next week.Many things are legal but bad practice.Will admitt on track homes we had no choice but to back stab to keep price down.

The better back-wire pressure-plate receptacles I've seen allow two wires per screw. So if you daisy-chain your conductors under the same screw, the connection doesn't depend on the little tab.480sparky said:

Wow, a guy could take that personal. :grin:
Does it need to be?
The ampacity of a conductor is directly related to how hot you want to run it, in this case we are talking less then a 1/4" of bare conductor that is heavily 'heat sunk' by the metal it connects to at either end.
Some times I pigtail, some times I don't. :smile:

So if the load that 'caused the fire' was plugged into the receptacle that caught fire, it wouldn't have made any difference if there was no pigtail. It wasn't the fact that it wasn't pigtailed, it was due to the termination either was poorly done originally or came loose for some reason over time. I'm not defending not pigtailing here, just pointing out that this instance has nothing to do with pigtailing.

No he is not joking, think of the terminal on a Square D breaker, it is a screw with a square 'washer' that allows you to place one conductor under each side of the screw. The conductors do not wrap around the screw.

Can I get an AMEN from the chior ? I have done very few jobs where I had to "cut corners" in a code leagal way. But a beat up price gets a beat up job. I read recently where a financial advisor was saying "the job you have to fight to get by price cutting , is a job you don't want"

I will give you an Amen to that.
If the customer fought to get the price down they do not deserve a Cadillac.

Actually there was no load on this receptacle fire started at.It was the result of some very poor workmanship.The load was further down the line feeding a sound system.All went fine as i had a few tools with me and wire nuts to make a temp splice of what was left.

But in all to many instances, they do get the Cadillac. Or an Avalanche, Hummer, etc. And they expect us to drive an '84 Mazda pickup and live under a bridge.

I lay money on the quality of the screw terminations were the cause of this not the metal tab. Poor quality work is poor quality work, tab or not.
AS FOR ME
