Generator Blows Control Board

i think our dishwashers control board is messed up. i think i heard i can test whether it is working with a multimeter or not. if so how can i? the cycles options a  pots/pans, normal wash, water miser, china gentle, and quick rinse. only the china gentle option works. the three other separate options a  high temp scrub, santi-rinse, and air dry. none of these work... also the delay hours options do not work either. and when i try to cancel or drain it, it will not stop unless u open it (but when u shut it, it starts until it finishes.) can all of this be fixed if i replace the control board? or do u think it will fix it if i change the fuses? or both? if not, what other problems could be causing this?
      

I'm buying a 12 lead Stamford generator, engine driven, and have a question or two about over current protection and ground fault protection.  I will normally have it wired for single phase 120 and 240 in the double delta configuration.  I may occasionally rewire it for 3 phase 240 in the series delta configuration.



For the single phase setup, what I've read so far leads me to believe I should have a main circuit breaker of about 125% continuous ampacity; it's a 10 kw generator.  Is that correct?  What kind of breaker do I need?  Should this main be a GFCI?  Do I bond neutral and ground?  This is a portable unit so I need to package a load center on the generator frame.  Can I wire one 240 receptacle directly to the main and two or three 120 volt GFCI's on it as well?  Or do I need another 240 breaker downstream of the main?  What should I be thinking about for swithching back and forth between single phase and three phase?  Alot of questions, trying to get smart and be safe.  Thanks.
      

OK, I'm an electrical dummy ...



I have finished basement w/a bathroom. We have an ejector pump off the bathroom that has been plugged into an outlet w/gfi since I've owned the house (10 years). There is also a booster fan for my electric dryer plugged into the outlet (has been the same for 10 years).  The only thing that has ever tripped up that outlet is using a hair buzzer in another outlet within the bathroom (but once you hit the reset its fine).

   

  This morning I realize the ejector pump was not sucking down the water from the drains. I looked at the outlet and realized it needed to be reset. When I reset it, the pump would run for a few seconds and the outlet would trip up again. Tried this a few times. Thought maybe it was an issue w/the outlet altogether. Neighbor suggested maybe it was an issue with the pump. Went thru various scenarios and bottom line is when I plug the pump into other outlets it works totally fine and once I do that and reset the outlet it was on, the booster fan works fine and the outlet does not trip. So, basically this outlet is tripping when the pump is on it but the pump is not tripping other outlets and the outlet works fine as long as the pump is not on it.

   

  What could be causing this? Why would an outlet that housed the two things on it all of a sudden continue to trip when the pump is on it but the pump is fine on its own in another outlet and the outlet is fine on its own w/o the pump?
      

I have a 120vdc treadmill motor that has a motor controller board and a transformer to operate it. My question is is there any way to rigg it up to a 12v deep cycle battery. I was thinking all i would need is some sort of step up transformer 9-1 if they make it or 10-1. I would aslo like to have speed control which i assume would work through lowering the voltage. It runs fine off the 12v batter just not near the rpms i need. I know it will drain the deep cycle very fast but im not worried about that.
      

I am considering adding solar panels to my home to generate electricity.  I will not add batteries however (to expensive) so when the grid goes down I won't get energy from the panels (you need a special inverter and batteries) so I want to add a portable gas generator for those, hopefully, limited cases.



I just wondered how the solar wiring gets interfaced into my system (breaker panel?) and can I later add a transfer switch or interlock switch when I add the generator?



Or should I do that at the same time (perhaps the interface is complicated)?



Thoughts?



Thx
      

On my second floor with a High / Low switch and a timer hooked up to it.  The fan works fine on high and the timer works - but if I try to put it on low it stalls out.  I can hear it try to work - it sounds kind of like trying to get a car to turn over.  It starts up, spins for a second and stops and repeats that cycle until I turn it off or set it to high.  The fan was installed when I bought the house so I have no idea how old it is or its brand / model.



Does anyone know what might be causing the problems on low, is it still OK to run it on high, even with the issues on low and is this something that can be fixed easily or does it require special services - electrician or otherwise?
      

The connector board for wirng motor broke in pcs when disconnecting wires. Im pretty sure what goes where still. But do I need the board? There is 1 wire that goes to board and nothing else.
      

I'm new to this site.  But would appreciate some troubleshooting.  I just renovated my kitchen, gutted and all, finished in the Fall.  I did not replace wiring to the dryer, nor tamper with it, to my knowledge.  We did have an electrician add a small fuse panel.  We did not add more appliances then before, added some lights, but mostly used the room to separate things out.  Had a mentor do the wiring, many years of experience, very tidy and careful work, though not electrician by trade.  We have a standard 200 amp box as far as i know.  The house is 100 years old, but the wiring isn't.



In October my mother in law heard a very loud bang.  The electric dryer had been running.  She smelled smoke.  At the dryer receptacle was molten plastic sprayed onto the wall, caused by overheating at that point, due to I don't know what.  I thought maybe I had knocked something loose in the receptacle when i was drywalling around it.  I can't remember now if the breaker had tripped.  The receptacle and plug were toast. 



I replaced the receptacle, I replaced the dryer cord, not the breaker.   The dryer worked fine until february, when it stopped heating.  I found a bad thermal fuse and replaced it, the very common two pronged white one. 



The dryer worked fine until early April when it stopped heating again.  I checked all the fuses/thermostats on the back and the heating element, as I had done the first time.  Nothing was bad.  I checked the voltage coming out of the wall, as I had done the first time, only this time I did it correctly and got a reading that told me to check the breaker in the panel, which had not thrown.  When I checked the voltage between the Nuetral Bus and the two terminals on the Dryer's 30 amp breaker I only got a good reading on one of them, telling me that the breaker was bad.  While at the box, i noticed that to the main breaker, from where the conduit comes into the box from outside, the nuetral wires are bare all the way up, no insulation, and at the terminal of the main breaker they appear to have all melted together, even a couple small pieces have melted off of the "bundle." 



Switched the range 50 amp breaker with the dryer, dryer worked fine, nothing was back fed either.  Bought a new 30 amp breaker for the dryer and installed it on Saturday.  Also on Saturday we were given a dryer, about 4 years old, same as ours, so i hooked it up and saved ours for a spare, which I deemed still good since it seemed the breaker was the issue.  New Dryer worked fine from saturday until today.  Now it won't turn on, though it didn't cut out mid load yesterday either.  The breaker did not trip.  I repeat, no tripped breaker.  I just checked the voltage at the wall and it seems to have that same problem where one side of the receptacle gets a reading of 120, and the other a reading of about 5.  The problem must be bigger than the breaker.  I am not an electrician, I am a welder.  I have gone as far as I could on my own.  Thank you.
      

Lookin to go camping electric free. I want to buy a couple car batteries just so we can hook up a couple of low watt bulbs. I already have a case for the battery so it will be portable. What kind of cables/wiring would I need to hook a light socket to the batteries? I'm guessing I would need an inverter too, am I correct? Would I also need some kind of controller so the battery wouldnt drain too low?
      

Been thinking I need a generator. Most likely a propane stand-by with electronic transfer switch. These things cost a bundle is it worth it?
