Cant find curcuit braker on my 97 saturn


It should be connected in series with a circuit. Since a circuit breaker acts as an "over current" switch it will be connected just an on/off would so as to "open" the circuit during an over current condition. This will remove power from the circuit.

All the power windows stopped working all at once, it is not the curcuit braker


It has a breaker but most of the time it's the main switch "driversdoor". The breaker will reset itself.

I have a thermosol AF 240 steam generator it is wired to a 50 amp GFCI breaker. It has worked for about a month, but now the breaker pops immediately. Checked for wires touching, replaced breaker, but...


Is the wire compatable for a 50 amp breaker. Also unit souuld be on its own dedicated curcuit, also how many amps is the service in the building, if your only at 100 amp it will not work.

A 60 Amp breaker (three phase) powers an 125 amp main lug 3 phase panel is that k or do i need a bigger braker. the wires are #8 THHN.


The breaker that feeds the panel and the wire are what determines the rating. The panel has to be at least as high as the breaker. It can be more, and no problem.The problem I see is that the wiring is undersized for the 60 amp breaker. You should have #6 wires or change the breaker to a 50 amp. If that is not enough for your load, you must change the wiring. It also depends on the type of wire. THHN will have the largest amperage, but if it is TW, it will be lower. Rule of thumb would be #10-30 amp, #8-40-50 amp, #6-50-60 amp, #4-70-90 amp and #2-95-135 amp. There are other factors, such as derating etc. but if you wanted to increase to 100 amp, I would run #2 thhn. Hope this helps.

Indicator lights flash but no movement


Tripped breaker or blown fuse. Breaker will be 50 or 70 amp located at rear of chair where joystick harness plugs in. If there isn't one there you have fuses and will need to take the seat off to locate batteries. Inline with the batteries are two 50 or 70 amp automotive type fuses or a fuse "block" mounted to the battery. If they're burn't they will need replaced.

I have a cutler hammer switch box that takes care


Is the motor new or old? Is this a recent problem or has it always been that way? What is the motor used for? Does the motor start and stop a lot, or does it run continuous? Is it constantly under load? Is this residential or commercial use? Approx.how long is the circuit? What size wire and breaker are being used? Does it kick out when it starts or while it's running?
The FLA (Full Load Amps) for that motor is 22 x 1.25 = 28 amps. In GENERAL, a motor like that usually requires a minimum #10 (THHN or THWN) wire on a 30 amp breaker. However, NEC does permit up to a 70 amp breaker (250% of the FLA) if the 30 amp breaker is not sufficient for starting.
Remember that it's the built-in motor overloads that protect the wire. Best practice is to use the lowest size breaker possible for ground fault protection that will still allow the motor to start. A 40 amp breaker would be permissible.
On the other hand, if the circuit is very long, you need to increase the wire size to #8 or larger.
If this is an old motor that didn't have this problem before with your current setup, then you may need a new motor, and increasing the breaker size is not usually the solution, at least not without a qualified electrician actually seeing and evaluating the situation first.

I have a bosch dishwasher model # I believe is SHX4AP05UC it keeps tripping my braker in the middle of washing wont complete a cycle any suggestions?


Adam, in order to help you, you must provide me with more info. What size breaker is tripping. What does the maufactor's manual reads about what size circuit it must be plugged into. If your house is a little old you probably have a 10 amp breaker that is tripping. If so than the manufaturer states theat it is recomamded to place it onto a 20 amp breaker. Only switch out the 10 map breaker to a 20 amp breaker if your the wire from the breaker is a 12 gauge wire.
Do not put a 20 amp breaker onto a 14 guage wire because it will most likely melt the insulation due to heat whichwill expose the bare copper wire which could lead to burning your house down.

One of 2 circut resets keeps tripping on our Generac generator


If it's tripping a breaker that usually means there is to high of an amp draw on that curcuit.

Are you plugging more things into that particular curciut (or just different but higher amp draw items) than you did last year?

It's also possible that one of the items plugged into that curcuit is wearing out and drawing more amps than before.

If you have an amp meter, plug everything back up just the way it was when you were having problems. Check the main wire going to that curcuit. (right at the breaker)

If your amp draw is greater or nearly the same as the amprating of that particular circuit, then thats your problem.
To many things/to high amp draw on one circuit.

If it is not near the amp rating, and you are getting proper voltage to the breaker, then I would replace that breaker.
