replacing old plug question

This is a fairly accurate visual representation of the inside of my brain three quarters into your explanation:


I could do better in person and with paper. My skills as an electrician are not compatible with my lack of skill of translating things into my computer.
 
You seem really big on the idea that this thing is a fire risk. Why?
I’m just pulling your leg.

You should get some experience in electricity. Not ragging on you, that receptacle you showed is scary for being 220v. I have a few 220 v tools in the shop, I have two receptacles at either end of the shop. I fashioned an extension cord with bulk 12/3 wire. It’s hard to accept that 220 only requires two hot leads and a ground, when 120 has a power, a neutral and a ground; the neutral and the ground end up connecting to the same leg in the service box.

I've already had that thought, and here's why: I can't get an electrician to my house to save my life. Remember that ceiling light fixture I was bitching about a few months ago? Yeah, still broken, and it's because no electrician will come out here.

So what does a good 220 outlet look like?

What's so hard to accept? 120 volt uses one leg of the alternating current and is returned to the neutral leg resulting in 120 volts, and 240 volt uses both alternating resulting in 240.
Nothing more dangerous about it. Both grounded.

Exactly like the one in your garage (for 15 or 20 amp service).

If your home has an electric clothes dryer then it has an outlet for 220v 30 amp service. If your home has an electric range (stove/oven) then it has an outlet for 220v 50 amp service.

I remember reading that thread a while back when I first came here. Figured you already had a fix. Think I had a couple ideas of what the trouble may be. Would have to look at again.

Like the one you have. But could stand to be replaced. Those metal tabs inside can fatigue over time from heat and make for a bit of a loose fit.
 
What do you think might happen if an extension cord is left plugged in?
People can trip over them; the plug can pull loose in the outlet and cause sparking, or something could fall on the exposed blades and short it out, or someone could touch it and get shocked. Over time, the cords can deteriorate; furniture can be placed on them causing damage, they are often run through windows and doors, which can damage them; people who use them tend to do so because they have more electrical appliances than they do outlets so they plug more into them than they should, basically using the cord as a permanent wiring method - honestly, any number of things. It's just poor practice and can be dangerous, which is why they should only be used for temporary purposes.

Code requires outlets in residences no farther than 12' apart - primarily to prevent the use of extension cords - and that due to the number of issues (man and material) they've caused over the years (which is what prompts virtually all of the National Electrical Code). The 12' rule is generally based on regulations limiting lamp cords to 6' or less. More outlets are required above counters due to the greater quantity of appliances in the kitchen than say in a living room or bedroom. And again, primarily to limit the use of extension cords.

Before I was of the mind that screwing with house wiring wasn't in my best interests. And my wife wasn't a fan of it because I'm good at helping her move heavy objects from time to time. But we've both come around to the idea that maybe I should try doing the wiring anyway, because we've both noticed that getting an electrician is basically impossible.

I just went out to the garage and plugged in the heater again. It's an extremely snug fit.
 
10 would be the safe bet for 4,000 watts, but 12 will suffice. The resistance was pointed out earlier. That's why I said go with 10 gauge if a long cord was being used. Eyeballing the photo, it looks like that machine wiring was 10 gauge, but hard to say for sure.
10's pretty hefty, particularly for a box that size which contains a switch; motor manufacturers will generally use a smaller size mainly due to the short distances involved to the load being served - my guess would be 12 gauge; but I could be wrong too.

Ah, okay. Well, a couple points.

1) All of my power tools that are permanently based are powered by cables that run along the wall or are otherwise out of the way of foot traffic (the images of the cable powering the automatic vacuum switch attached below).

2) The jointer and the planer are mobile because they would have to be rolled into the place where my car is before being used. That means that at the end of the day both of them are unplugged and rolled back into their storage spaces.

Residential electric isn't to difficult to do right. If are handy enough to do woodworking, I think you could handle it. Pretty much boils down to hooking up right(not much to it) and making secure connections. Plenty of online resources out there to light the way. Pun intended..

Say it's good then.
 
Knew an old timer that was taught to install outlets ground at the top so if the cord wasn't in tight nothing could drop and lay across the hot/neutral.
Yep, precisely. That's a good idea and "generally" standard practice for situations like workshops, or working studios, some kitchens where the likelihood of that occurring is more prevalent. Another option is horizontal with the neutral blade on top. Of course, it's also standard practice these days to install the ground up to indicate a switched outlet (where all others would be ground down), so I think the practice has sort of waned over the years in preference to what's done today.

First rule is always DO IT NEAT - and that passes on that score. Plus, you're now aware of potential issues so will treat the cord better.

That said, it's generally not a good idea to strap extension cords as they do deteriorate over time - though honestly, treated right, you'll probably be ok. I wouldn't worry too much. I would unplug it though when not in use.

One thing you might consider, since your walls are finished, is a surface conduit, like Wiremold 500 or 700 (all you'd need is the 500). Only "hard" part for you would be re-wiring the wall outlet, so you'd want to find someone who could do it properly.

You know what totally screwed with my head? Maximum Overdrive, that shit movie from the 80's. It completely traumatized me. To this day, when I need to switch blades on my table saw and I unplug it first, I'll still flip the switch on the table saw anyway to make sure there isn't a "residual current." Has the table saw ever turned on after I've unplugged it? Of course not. But Maximum Overdrive gave me that phobia and this is who I am now.

That's a really great idea and I'm going to do that.

My go to's on such questions are either "Works fine, lasts long time" or "PFM" (Pure F'n Magic)

A gazillion old 1950's window air conditioners managed to use those old outlets just fine.
 
👍 And you can get everything you need at Home Depot or Lowes.

Good luck!
Here's why your suggestion resonated with me so much: I ran a cord to my shop table in order to wire it (power strip on every corner = awesome), and a wire running along the floor, even if not where foot traffic is, was impossible to avoid. I taped it down with duct tape and even covered it with red electrical tape for good measure, but I always hated this solution, and the wiremold really does a lot to fix that.

Here's that solution I was talking about. Is it the worst solution? No. Is it a good solution? Obviously not.

Yeah, not the best solution, but it can work for you probably indefinitely.

I made something identical to this:

iu


It's a quadplex outlet in a 4-square deep steel electrical box with raised cover. I attached it to a rugged, heavy duty 12 gauge SO cord (much more rugged than a standard extension cord) with a plug. It's real handy and I can kick it out of the way when not in use. Incredibly durable, but it can still be a trip hazard.

Another thought is overhead. Don't know your setup there, and not always feasible, but that too is worth consideration.

Well, I feel like that's kind of kicking the can down the road, because I've got to get that cord from one side to the other, you know?

Yes, I did consider that solution, but a dangling overhead cord seemed like a real nuisance.

True dat. :)

You could perhaps consider a cord reel. You'd still have a string or cord hanging down to pull down the outlet, but not as obvious or invasive.

Obvious downside though, cuz cord reels can be pricey, depending on what you buy - and they're not for situation either.
