240v connectors
I'm building a spot welder, using 2 microwave oven transformers &
running it on 240. On my welder & plasma cutter I've used dryer plugs and receptacles, but the unplugging is a bit of a hassle and I'd like it to be easier with the spot welder. A twist lock would be nice, but even on eBay that would be at least $25 for a pair. (This is a junk-box project and it would really hurt to spend that much on the *plug*.) Does anyone have a good idea for a 240v, 20a connector? Bob |

If you really want to be cheap, you could replicate the idea with a loop of plastic strip cut from a $1 flexible cutting board and a well placed and insulated pop rivet or two. |

Bob I have a couple older 240 volt machines and the plug on them looks like a regular AC plug except that the pins are horizontal rather than vertical. I made an extension cord for them and I believe the plugs are rated for 20 amps. And they were fairly cheap down at the hardware store... Jerry |

Does anyone have a good idea for a 240v, 20a connector? Any large hardware or home supply store should have a plug/socket that looks like a regular old 120 volt set, but with one of the blades rotated 90 degrees. I'm pretty sure it's good for 20 amperes and I've been using one on my Sears compressor for about 25 years. |

Does anyone have a good idea for a 240v, 20a connector? Go to your local hardware store or outlet of The Borg, they have good old straight-blade 20A 240V plugs and receptacles for not much more than 20A 120V. Looks just like a standard wall outlet, but both blades are horizontal. U _ _ They even make combination duplex receptacles that have the 20A 240V on top for the window air conditioner, and a 20A 120V on the bottom for a convenience receptacle. (Special order or wholesale house.) Also handy for installing in the kitchen of a gourmand with 240V European appliances they've brought home - just change the cord cap. Don't try to skimp on this one and use a 120V receptacle on a 240V circuit - guaranteed someone will walk into the shop and plug an extension cord into that outlet without thinking, no matter how big a warning sign you hang in front of that outlet, and they'll only figure it out after they fry something but good. You might even do it - once... -- Bruce -- |

As soon as I walked in I saw that the problem was caused by someone damaging a combo outlet, and trying to replace it themselves. They used a standard duplex 120/15 outlet, without breaking the tab between the two line terminals. Needless to say, the circuit breaker was bad in the 200 A three phase panel a few feet away. I broke the tab and moved both sides of the line from the two pole breaker to a spare 15 A single pole, and reported the damage, and tampering to their school board.

A few weeks later, the neutral buss in one of the breaker boxes went up in flames. After that, I started checking EVERYTHING. So far, I've replaced over 20 outlets, and four breaker boxes.

240v connectors
Thanks, but my source or sink is neither that large anymore.
The 60 amp ones were used but we upgraded once I started working on the big stuff. My GAAS IC drew 70 Watts itself and had liquid cooling on both sides of it and the whole board of GAAS, ECL and CMOS Gate Arrays and IC's. If I put in a sub circuit maybe. But my voltage conversion case (wall mounted) has 3p already in sockets. Martin Martin H.

240v connectors
Normally they sit behind the machine until it needs moving. Once in 5 or so years.

At 100A / phase complete cable assemblies are just to heavy to handle anyway. ----== Posted via Newsfeeds.Com - Unlimited-Unrestricted-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |

(20a 250v extension cords) Got any plugs and receptacles for 220v single phase? I could use a couple more L6-20 pairs for my shop. I do not think so. i Let me check this weekend. Ive got a milk carton filled (overflowing) with twistlock 3 conductor males and females. Tres bien. Danke, senor. Da nada mon ami. Gunner |

I bought a set of 6-20 at Lowe's - $10. Bob BTW, Lowe's vs Home Depot: Lowe's website with had all their electrical products on it, HD's has none. It's nice to be able to check availability & price before driving there. |

So far, I've replaced over 20 outlets, and four breaker boxes. Several circuits are disconnected from the breakers, till I can rip out a floor to find out why a couple outlets are intermittent. You mean you aren't supposed to bury an old and unwanted receptacle box (with hot wires and a receptacle still in it) inside the wall when you remodel? Gee, I never knew... ;-P Turn off the panel and stuff a fishtape (with leader) down the conduit - get a distance to the buried box and you might even be able to hear roughly where it is. Then stuff the fishtape from the intermittent outlet direction and see if they both go to the same place. Some days you can avoid poking great big holes in the drywall at random. I have gotten really lucky a few times - I've seen the small bump in the plaster where they filled in and painted over the outlet box, and with care you can chip it out so clean they don't have to repaint. -- Bruce -- |

I got carried away with the coolness of twist locks. I bought a set of 6-20 at Lowe's - $10. Twistlock has it's place - stuff that's overhead, high abuse, or three phase where the only widely available form factor is twistlock. Straight blade is just fine for the small stuff. BTW, Lowe's vs Home Depot: Lowe's website with had all their electrical products on it, HD's has none. It's nice to be able to check availability & price before driving there. But that online check only tells you how many the inventory computer thinks should be there, the count was as of close yesterday, which often has absolutely no basis in reality... Someone came in and bought them out at 8 AM, sometimes the inventory count is borked, some items are very popular with shoplifters. I've been burned too many times when they say "Come On Down, the inventory says 75 on hand" and the shelves are bare. You have to call up and have an employee physically put his hands on the item before you drive to the store. And get an employee name. -- Bruce -- |

You mean you aren't supposed to bury an old and unwanted receptacle box (with hot wires and a receptacle still in it) inside the wall when you remodel? Gee, I never knew... ;-P What box? I found wires wired nutted together with NO box, inside a wall. Turn off the panel and stuff a fishtape (with leader) down the conduit - get a distance to the buried box and you might even be able to hear roughly where it is. Then stuff the fishtape from the intermittent outlet direction and see if they both go to the same place. What conduit? Its all Romex, and a 4 inch crawl space. Some days you can avoid poking great big holes in the drywall at random. A plastic cap from a 2-liter pop bottle will force fit on the end of the 3/4" PVC conduit. It keeps dirt out as you shake it around to run it through a crawl space. If that doesn't work, cut a hole in a tennis ball so it will slide over wires and pipe, to where you want it. I've pushed a wire 65 feet this way, under mobile homes for CATV and telephone station wire. I have gotten really lucky a few times - I've seen the small bump in the plaster where they filled in and painted over the outlet box, and with care you can chip it out so clean they don't have to repaint. I pre wired the burglar alarm, fire alarm and background music systems in a general contractor's new office building about 25 years ago. The drywall people mudded every box, and did a textured finish over it, bitching that there were "Too many wires" in the walls and ceilings. I called the contractor and told him what they had done. He said, Don't worry, make as many holes as you have to, to find your boxes. The drywall forman started to complain, and was told to shut up. I smiled at him and picked up my brick hammer, and slammed it into the wall, right into the first box. The guy was pale as a sheet! I smiled and told him, "I won't be so careful, the next time! He didn't notice the marks on the bare plywood floor directly under every one of our boxes. He was freaking out as i ran around smashing holes, and finding each box with a single hit. He looked like he was going to have a stroke. Another job, a sound system in a new church. The 1/2" conduits for speaker wires were plugged with blown in insulation. There was too much to work the fishtape through, so we went back to the shop and brought our BIG air compressor to the site. I found some of the large rubber plugs from the freon lines, and cut a hole in the tip. Then shoved the plug against the end of the fitting and let the pressure build up. It was a beautiful sight! It was snowing in the chapel as the insulation finally let loose and was blowing out of every pull box! -- Service to my country? Been there, Done that, and I've got my DD214 to prove it.

It also doesn't tell you that those 3 Square D breakers it says they have are mixed in with the GE breakers. A *huge* annoyance at the Borgs. But it's a start - the HD website is totally useless.
