My client has 19" in rack mount ups's circa 3kW. The building has generator back up however when we drop the mains and put the building on generator the ups do not see the generator hence stay on batteries. If allthe buildings load is switched off with the exception of the IT rm (upss) then the upss do pick up on generator.

It sounds like someone wired your outlets wrong. I actually just found the same exact thing in my server room. All other outlets in our office are covered by our generator backup power except our server racks. I would suggest contacting the original electrician that installed the wiring to come out and check it again. Something is clearly wired wrong.

Westerbeke 3kva generator cuts out when kettle boils

Depends on the Generator size. It may well be that it has a suggested 3kva max output. Generally a little overrated. Your 3Kw kettle might be over 3Kw input.

These things mean the generator safety cutout operates just below 3Kva. The generator would be fine with a short time 3KVA output only. better for it to cut out than the cook!

Trick would be to have a 2kw kettle or a 4kva genny

This is a typical situation for a warn Powerpile generator. Your fireplace works by this generator generating heat from your pilot flame and converting it to less than 3/4 of a volt or 750mv. Your gas valve will eat up half of this electricity when running. So when you Powerpile gets warn it might only generate 400mv and when the gas valve turns on will bring it down below 200mv. This will start to drop once the main burner turns on and once below 150mv is no longer able to power the gas valve resulting in the main flame to go out. Minutes later the generator will build its power up again and repeat the cycle. The generator looks a little thicker than a crayon and has a red and white wire coming off it. They are easy to change but the tight spaces on a fireplace can make it very difficult.

What size generator do I need to run my Kenmore refrigerator model 253.68802011

A 3Kw generator will power most refrigerators unless you add too many other devices to the circuit. There is a surge of electricity needed at start-up of any compressor.

There is a button on the top receiver bracket on the left side... when you take the rack support bracket out you will see it. Take a damp sponge and go over that area, pressing the plunger/button in several times. That should do it. Sometimes grease build up can prevent the button from popping out all the way, so the oven thinks that the racks are still in there.

I have recently purchased a Eurolite 6U 19 Rack Mount Amp Case for my Marshall AS-50D combo amp but I need instuctions on how to pack the amp into the case.

When putting amps or ANY heat generating devices into a cabinet, make sure there is FREE airflow around and especially around heat sink fins. Sometimes it is necessary to leave a gap between amps that are stacked in the cabinets.

I can't remember if you plug in the generator to the electric panel first (with power turned to the generator and off of the main line feed) and then start the generator, or start the generator and then...

OK, by talking about a plug, I am assuming you have made a double male plug to hook the generator to the electric panel. This is not really advised, because it is so easy for it to be plugged into an outlet by someone not knowing what it is far, and getting electricuted. Now, away from preaching, and to helping.
It is best to hook it to the generator and then crank it, so you are not dealing with a load when you plug the systems together. When your power is restored, it would be good to install a plug to your electrical box and have it go to a disconnect like is on your outside A/C unit. It moves you away from the hot wires.
Hope your power is on soon!

Maytag Skybox "Is this normal?"

I have intermittent problems with one dispenser and disassembled the system1.gif and swapped drive motors for the dispensers. The problem followed the motor. shows that they sell the individual rack assemblies but I have not yet ordered one. I am trying electrical supply stores to see if I can just buy the motor but I doubt they will be able to track it as it has no markings.
