Voltage drop scenario/amperage question

Hmm ... I prefer -40 degrees. There, it doesn't matter which of those two systems you use. :-)

Enjoy, DoN.

Correct on all counts but the typical issue you run into. The install was correct for the 60's. But energy costs keep pushing toward insulation and sealing the house. What was safe enough 40 years ago is NOT safe now. Used a standard gas valve with thermocouple but no pilot light connection. Since the main gas valve controlled the main burner, there is no reason the pilot light could (should) not be hooked up to the downstream side of the furnace shutoff.

The rest of the system uses controls that are just not in the textbook for all the young HVAC techs. I understand it, it's a dozy (Honeywll 829 system ring a bell?). A neighbor has the same system, only on 3 furnaces. I've told him that if it goes down, he better have me talking to the tech or the bill will exceed $10,000 to get it running again.

Hey, that's time to go out and play in the snow. At that temperature, I can not only blow snow over the hedge, but all the way across the street onto "Dim Jim's" driveway. Gerry :-)} London, Canada

Can you make me a deal on a few hundred cubic km of snow, free shipping? We could sure use it in the Sierra.

Well, I tried it today, and the 100 footer worked fine. Went to HD and got two metal boxes and welded them back to back for a 220v on one side and four

110v. outlets on the other side. Well, I didn't do it, but my electrician did. HD geek said it wasn't legal, and couldn/t be done. Well, it can be done, but not sure about the legal. It is a temporary setup I'll use for an hour, then sit in the garage for two weeks with no power on it. I'm out tomorrow to weld up some columns and get some of this crap out of the pipeline. Watch for me in the news.

I once pulled 500 amps out of a CyberTig 2, using 12ga stranded

Not for very long, just long enough to stick a piece of 6011 completely through both sides of a 2.5x2.5" piece of thickwall tubing.

About 120 amps at 240, 3ph. Didnt get very warm, though the piss dribbling down my leg was warmish.

Had the remot control pot wired backwards......low turned out to be "full on, full military power"

I just ran 2400lbs of 2/0 for a customer, and am fixing to hang about the same amount of 10ga.

Im glad Im not providing materials on this job.........

I admire your initiative Steve, but that ain't kosher. The green ground wire is only there to conduct 'fault' current to trip a breaker in case of a short. You are forcing all the return current for your 110 V outlets through your safety wire. Not good.

How many spaces on that 200A panel? Are you really maxed out as in out of capacity, or just out of spaces? Remember, a second service comes with a second monthly service charge forever, so it far cheaper to use appropriate sub panels rather than a separate service.
