Often the breaker is in the main service panel and so there is no way to cut power to the panel. This means they will be working with live current and exposed electrified conductors. This is dangerous work and requires caution and appropriate safeguards. If you don't have a lot of knowledge and experience with this kind of things, you should call a professional electrisian.

On jacuzzi, circuit breaker trips when turned on. What could be the problem?


Is it simply a circuit breaker, or a safety switch as well?

If just a circuit breaker, something is causing a too-high electric current flow. If a safety switch, there is a fault to ground somewhere in the jacuzzi.

Either way I would not get in it or turn it on until an electrician has checked it over. With any device where you sit in the water, you need to have high confidence there are no electrical faults waiting to zap you. I'd call a jacuzzi outlet and ask them for the name of a knowledgable sparkie.

That's about the best we can tell you at this range.

Circuit breaker trips each time I turn it on, could it be bad?


very bad
it indicates a dead short or if your circuit breaker is an ELB ( earth leakage breaker ) it will be shorting across the insulation of what ever is in the circuit
IN one instance the dead short or possible over load will require a larger breaker if what ever was added is causing the fault
in the second instance it could be water contamination of an electrical component
the fix is not for diy people so get in an experienced electrician and be safe

What is the proper way to whire up breaker box


I'm an electrician and your broad, simplistic question scares me too much to even provide an answer out of fear that you think you're going to learn everything you need to know about doing this work properly and safely with the answer you get here. It's people that post questions like this that really have no idea just how far "out of their comfort zone" they really are. Let me tell you, you're so WAY out it is deadly. Please don't take this as an attack - as it is not in any way, shape or form. YOU really need to call a licensed electrician to perform this work for you. Wiring is not a hobby. Good day.

Instruction manual for FP 100 circuit breaker


Hi - I'm an electrician and may be able to help you with your question.

FPE or Federal Pacific Electric brand products are obsolete, and the company has been out of business for decades. There's little to find about these breakers now as a result. Different companies have either bought the company or made replacements over the years, including Reliance Electric, Challenger Electric, Connecticut Electric, American Electric to name a few.

To the dismay of electricians everywhere, the U.S. Consumer Product Safety Commission (USCPSC) investigated allegations of unsafe FPE brand circuit breakers - but could not establish that the circuit breakers pose a serious risk of injury to consumers. Check these links for the USCPSC report and opposing views:

http://www.cpsc.gov/cpscpub/prerel/prhtml83/83008.html

http://www.prestigeelectric.net/downloads/hazardous-fpe-circuit-breakers-and-panels.pdf

http://creagerelectrical.com/federal_pacific_panels_stablok.html

The damage was done however. Electricians avoided installing this brand do to problems noticed. Eventually electricians began to jokingly call the FPE "Stab Lok" breakers as FPE "No Trip" breakers. They were horrible and would take a much longer time to trip in an overloaded or short circuit condition than any other circuit breaker sold. Most electricians - myself included - would try to convince property owners everywhere - to replace these panels wherever we found them. They were just that bad; in spite of the USCPSC findings.

There are many different models of FPE breakers. You should find the particular model on a label that is affixed to the breaker. Use this number when asking for information specifically about it in a follow up to my answer or whenever seeking information from other sources.

I hope this helps!

Do you have a wiring diagram for the square d qo250gfi


Any 2-pole GFI breaker typically supplies power to a dedicated balanced load, such as a pool motor or heater. Any load imbalance between either power leg (L1 or L2) and/or the neutral (N) will cause the breaker to trip on ground-fault, ie, it senses more power is going out than is coming back, so it must be leaking out somewhere and the breaker trips.
The load conductors are connected to the breaker under the brass colored screws just like a conventional breaker and the white wire pigtail from the breaker is always connected to the neutral (not bond (green)) buss bar whether the load circuit has a neutral or not. If the load circuit does have a neutral, that white neutral conductor connects to the GFI breaker under the chrome colored screw, else, this screw is left empty.
If you have any questions or hesitations, you really should have this project performed by a licensed electrician. GFCI protection is a life-safety issue and any improper installation defeats this protection.

Renting old house with old power box uses 'plug in fuses' , doesnt have cut off safety switch ,i heard that i can by circut breakers to stop any surges and plug them into fuse box ,does that sound right ?...


Wow, all due respect, but someone would really be negligent to offer you a solution to this problem. An electrical panel isn't something to mess with, especially if you're asking these type of questions. Contact a professional electrician in your area or run the risk of electrocuting (that's DEAD by electricity) yourself. Good luck, and please be safe.

Breaker malfunction- Breaker won't restore power to the circuit


To do this safely you should call an electrician. No way I can give you complete instructions that will be sure to be safe because I can't see exactly what the situation is that you have. But the basic steps include: turning off the main, understanding that you are about to expose the feed lugs TO the main which are still LIVE (and giving them a wide berth!), carefully removing the cover, CONFIRMING that everything else in the box is NOT LIVE (use a non-contact voltage detector - $15 or less), removing the wire from the old breaker, pulling the old breaker out, plugging the new breaker in, connecting the wire to the new breaker (nice and tight), replacing the cover and then turning the main back on.

Old residential fuse box


1.One fuse blows all the time?
2.You changed the main fuse, or one of the main fuses, and get no results?

Suggest seeking a Professional Electrician Pronto!

Fuses are a Protection device. If a fuse blows there is a problem. If the same fuse consistently blows, there is a Definite problem!

If changing The main cartridge fuse, or one of the main cartridge fuses does not bring about a change,

THERE IS A REAL PROBLEM!!!

Many times I've seen where a house has been added on to, and the electrical system has not been upgraded to match. A fuse panel definitely suggests this. Circuit breaker boxes have been implemented for a long time, and in the US, a 150 amp service panel is the minimum. (2008 NEC Code)

Someone who wasn't a licensed electrician, (Or someone who was a licensed electrician, but who
who should have had their license pulled), has attached wiring where it shouldn't have been.

More than one Load wire going to a protection device, (Be it a fuse, or a circuit breaker), is asking for trouble.

Each circuit should have it's own fuse. Each room should be on one circuit. Lighting should be at least on two circuits. At the Minimum!

(If the fuse blows for a lighting circuit, and there's a storm going on outside, you sure don't want to be hunting around for a flashlight in the dark, when it's easier to find a room that still has lighting. Find the room/s that still have electricity, and flip a switch on)

Kitchens should have many circuits. One for every three receptacles, using a 20 amp breaker. One for a microwave. (20 Amp) One for a garbage disposal. (20 Amp) One for a dishwasher. (20 Amp) One for an electric stove, (If used). (40 Amp) I even like the lighting to be separate. On it's own breaker. There should be a GFCI used, if the receptacle is within 6 inches of a water source. (Ground Fault Circuit Interrupter)

The NEC Code is a MINIMUM. It is implemented to keep people safe.

Your fuse box may have many circuits tied to one fuse. Common practice used in the past, and a Very Unsafe One!

The following is for INFORMATION PURPOSES ONLY!
It is NOT an advisement to repair!

The fuse panel may be under a leaky roof, causing the contacts for the fuses, (Round individual ones, or the main cartridge fuse), to become corroded.

If you have a corroded contact surface, you will have resistance. Resistance causes Heat. Heat causes Fire!

There may be loose wires where they connect to the fuse holders. AC electricity vibrates. Alternating Current. It flows back, and forth on one wire.
If the screws on the fuse holders, have come loose from the vibrating of the AC, there will be resistance.

I've seen where screws have come so loose, that the wire was just about to fall off. The homeowner was lucky I called a professional in.

There is no way I can safely guide you in a solution to fixing your problem, Other than suggesting seeking a professional electrician.

The Main reason I posted this, is to Implore that you get professional help for your problem. You have a very dangerous situation, and I fear for your safety.

I realize a professional electrician is not cheap, and the world is an economic crisis, but we are talking about your life here, or maybe more than one.

You need to put in what we call a sub box. This should be done by a licensed electrician, but if you really want to do it yourself you will need a distribution box some wire and it has to be connected directly to your main lags from the meter box, this box will have a main breaker built into it and spaces for additional breakers, depending on your existing wiring the electrician might chose to wire the additional box directly to your meter base and not your existing box. Either way you really should seek local professional help on this project, just for your safety and to satisfy your home-owners insurance.

Have a great day..

Circuit breaker


There might be a short circuit in your wring for that circuit.
You can unplug all your electrical items from that circuit.
See if the circuit still turn off.
If it does, it could be the wring or the equipment that is permanently wired in.
If not, you can plug in one item at a time, turn it on to determine which electrical item is defective.
