Uhh.. I was saying "I know" to your own statement "a neutral is considered neutral for a reason" And only you brought up a higher voltage circuit with two hot wires from the positive and negative...
Well to be clear you mean the electrons flowing to and from the end of a "hot" wire can do work with another "hot." To use your own argumentative logic one might say "Not so. Another "hot" from the...
I know. And its because it's at neutral potential relative to ground. That is the one and only reason.
Yeah sorry I read most of the thread and there was some very good informational explanation about the center tap of the utility transformer being connected to ground, and the neutral wire of a 120v...
BBerne I was quoting the question of the originator of this thread not asking a question. I am not discussing any theories. The original question of this thread is why a neutral wire and a live wire...
My question is, if we are using AC current, then in the next half cycle, the live wire will return the current from the appliance and the neutral wire will bring current to appliances. Am I right?

I get 1 hr s.t. per weekday on call, 2 hr per weekend day- any call out cancels the on call pay for that day and you get paid overtime for as long as you are at jobsite. Supposedly I can turn down...
Small market. Large equipment. Good, I was worried when you said you were resigned to be a bottom feeder and only a few lucky mechanics had good jobs. If you are talking to the people who cash the...
You have uttered not a single word which anyone reading would consider evidence that the workers who, like you and Milkman are resigned to always making short money, and don't ask their employers for...
help what? I was discussing the ratio of what companies charge compared to what they pay workers. Since the union rate is an available yard stick I used that. What are you claiming to have explained...

So far I only mentioned union as a reference point to wages, you somehow are arguing against unions with a guy who hasn't said anything positive or negative about unions. Why are you doing that?

Are you being sarcastic when you say "i love hearing stuff like this?" It needs no explanation. Milkman said he is destined to be a bottom feeder when it comes to how much he can command in the...
Mlkman, The guy who cashes the customers checks at the company you work for I'm sure is a smart, hard working likeable person. I can assure you that he has thought about what type of employee he...

Thanks for the help. Thee building owner called the installing contractor back after my co worker suggested checking the size of the evap coil and txv, they apparently are willing to try to make it...
Doesn't sound like it total, a grounded 24 volt transformer will read 24 volts on one secondary terminal and 0 on the other I think. check for 24 volts on the green and yellow wires coming from the...
A guy I work with called me for assistance with trouble he is having with a 3 ton 410a split system. He found the unit (installed by another contractor in 2010, an off brand unit that we can't tell...
This isn't a house, it's a store with 20 foot ceilings, I posted in residential because the installing contractor (not me) used twinned residential furnaces and 6 ton c.u.'s. Two systems total (4...
Worked fine in cooling and heating. And I thought of the short circuit problem - but the xfrmrs are hard wired (through a plug) to the incoming hot wires which are wire nutted together in a 4 by 4 on...
The jury is apparently undecided. I'm giving it a go without the twinning control. Can't think of any difference in operation besides when one fan fails the other will continue to run, with some...
I'm a chiller guy helping a friend whose twinned furnaces stopped working (in cooling season). Someone (he thinks the landlords handyman) jury rigged the wiring, probably to get the unit running in...
" the switch in the breaker would trip just before
transition & remake as soon as the compressor shutdown. "
So was the remedy a whole new breaker? I knew those breakers had switches in them, but...
I know, and since you probably weren't wearing one of those bomb squad type arc flash suits while opening the panels of your chiller during the troubleshooting you did, you need that limit on the...
Compressor heaters: I've noticed these things are notorious for ground faults that test out good with a typical high impedance DMM, but will intermittently and randomly break through to ground and...
Yeah to the barrel heater if you've got them, but these things also have little bayonet heaters for the compressor housings, which if they have an intermittent ground fault will do exactly what you...
If the slide valve step is 75 the compressor is (at least as far as the micro knows) fully loaded. Problems could be the position indicating pot is out of cal (doubtful if two compressors on the same...
I guess I might sell him the cheapest used 100 ton chiller I could find with a comfortable mark-up, a big deposit and an as is warranty. He surely isn't going to do any better.
Here's the EPA page...
I had one do this once, a rental. Drove me nuts until I checked the tightness of the white neutral L2 wire terminations coming off the compressor contactor/s. The loose common wire was intermittently...
But I did see one's valves wreck. I don't know how many times it survived starting up with the suction pipe full of liqiuid, but it finally gave up the ghost.
When the composite valves of the Copeland discus compressor self destruct (uncommon but I have seen it) the oil gets all gray. Change the oil and clean the sight glass, but shoot the heads with an...
Carrier mechanics never really used one, just the service manual that has the clearances listed. For the impeller clearance part that others are issuing dire warnings about, we used to lay or hold a...
