I disagree. There are a lot of qualified folks here, and incorrect info is quickly weeded out. Besides, a lot of the same folks that frequent Holt's are members here.

What we have here in North America is NOT 2-phase, it is single phase, or more accurately split-phase. Calling it 2-phase is not only wrong it is misleading since 2-phase does exist but is extremely rare. Do you have an example of one of these older straight 240V dryers?? In all my years I've...

I'd bet $5 that this is not from a loose wire. I've seen this problem MANY times and it is almost always a loose fitting prong. They are cheaply made and the expansion/contraction over the years causes the prong connection to loosen.

We need to stop thinking that the earth (ie:ground rods) have anything to do with equipment grounds. Ground wires run with circuits (equipment grounds) are VERY different animals than grounding electrodes (ground rods) and serve very different purposes.

Older sub-feed circuits to a DETACHED structure under certain circumstances allowed the ground to be bonded to the neutral, same as in a main panel. This is where the equipment ground came from. Newer feeders, and those within the same structure, require a dedicated equipment ground run with...

First off, you cannot just go swapping "angled blade" for "straight blade" "220" receptacles without confirmation of what wires exist and what the amperage is. There are 240V receptacles and 120/240V receptacles. Then there is the amperage. The configuration of the blades determines both...

+1 You beat me to it.

It is not a recommendation, it is mandatory. The receptacle is what caused this problem. It ***** how often we see this with dryers.

Ground rods do not need to be accessible in any way. They can be below concrete, buried deep, etc.

Current codes require ALL 120V 15 & 20A receptacles in a garage to be GFI protected. I would find the first receptacle in the string in the garage and put the GFI there, using the LINE and LOAD terminals so everything down stream is protected.

Nothing will "short out" because of rain or snow. The issue is damage the water will do long term, or even short term is there is a bad enough leak.

WHY would you think this?? That is a 4-space meter/main enclosure. Both of those breakers are mains.

Then it's a semantics thing. Around here there are 90's and large radius 90's. BOTH are sweeps.

As long as you are buying your fittings in the right place you will only find electrical sweeps. I get the impression when you say "regular" 90 deg fittings you mean plumbing fittings. A "regular" electrical 90 IS a sweep.

This! Unfortunately, we will always get folks stuck in the past that will not acknowledge that things change. We will keep hearing the 40 year old arguments.

OK, but aren't these plug-in space heaters?? Art 424 does not apply.

I know what you are asking, and it does NOT exist for one reason, it is not code complaint. A 30A receptacle is a 30A receptacle. Everything you are proposing is anything from not code complaint to downright dangerous. You are looking for a cheap easy solution. There is one. RUN TWO 15A OR...

This is a really, REALLY, bad answer.

NO. You 100% CANNOT do what you propose.

It will only not meet code if the load is or would be considered a continuous load, as per the NEC definition. The key word here is expected. If these heaters will only be run together for a couple of hours at a time maximum then it is FINE where it is.
