    100 kw gen set no voltage

    Ditto jbartos. It is always best to totally exhaust the manual on the device, then tech support, prior to re-inventing the troubleshooting wheel. The Internet is a rich supply for outdated manuals, FAQs, postings, and even chat sites for various brands. Further, the device's own company tech...

    I was currently troubleshooting a p

    Hi! Bottom line, shotgunner, there is a capacitor and/or motor involved in the aberrent activity somehow. You have already stated that the line is pure when nothing is plugged in.

    Elctronics circut for hendel my home electric SWICHS?

    Mazhar: Several companies here in the United States (Leviton, for one) make what is called an "occupancy sensor". This device normally mounts in a standard switch box, which would of course be mounted near a door leading into the room in question. This sensor can tell when there are...

    220 VAC motor-Only One Lead Direct To Motor

    Wow. Unfortunately, this happens a lot. Single phase 220v can be switched through only one leg, but it is not advisable; and in motor applications like you describe it violates NEC. The reason you see this so much I suspect is that single-pole relays are cheaper than double-pole. The problem...

    Safety relays

    Question: Are you referring to fail-safe scenarios, redundancies, switchovers, combinations of the above? All three (and others) can be used effectively in safety override circuits. As mentioned by others above, context is key. What's up? General knowledge, or do you have a specific application...

    Don: Lots of good ideas have been mentioned. Several items need to be nailed down, however. (1) System Ground - is the main panel grounded according to Code requirements? There should be a ground rod (with rare exceptions) driven eight feet into the ground with a preferably solid bare copper...
