As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.

Can you use 14-3 wire on a 20amp breaker?

No. A 20 amp breaker needs 12 gauge wire.


If you have a 125 amp breaker box on the pole with a 125 amp breaker going to your house and you get a hot tub that needs a 60 amp GFI breaker would that overload the box?

It depends on what else you are running in the house. Add up your amperage to see if it is more than the 125amp rating. Which should be below 105 amps constant to keep from overheating the main breaker. If you are not running a big central ac system or a electric oven and water heater you should have no problem running the hot tub.


How much does a shunt trip breaker cost?

The cost of a shunt trip breaker depends on the amperage and number of poles the circuit connected to it needs. The cost of the shunt trip over a conventional breaker is substantially more.


What makes a circuit breaker go bad?

A circuit breaker can go bad from being tripped too many times. Many people don't understand that the tripping of a circuit breaker indicates a problem that needs to be corrected. They usually just reset the circuit breaker, leading to a very common second (or third, or fourth) trip. Circuit breakers tripping are for the prevention of fire due to excessive heat in the circuit. They're not supposed to be tripped repeatedly. This can wear the breaker out. Believe it or not, I've also seen circuit breakers fail to re-energize after being turned off. I speculate this was actually caused by the breaker never having been cycled (it was a main breaker), and the time elapsed since it was installed. Electrical equipment doesn't last forever. It's the same as anything else.

What size breaker needs to be installed for 15000 watt 240 volt heater?

A 15000 watt 240 volt heater would require a 62.5 amp circuit breaker. To accommodate this exact load, you would typically use the next standard breaker size above 62.5 amps, which is a 70 amp breaker to ensure safety and proper operation of the heater.


Can you use a 20 amp breaker if the amp rating on a heater is 21 amp?

No, it is not safe to use a 20 amp breaker for a heater with a 21 amp rating. The breaker should be rated at least equal to or higher than the amp rating of the appliance to prevent overheating and potential fire hazards. It is recommended to use a 25 amp breaker for a 21 amp heater.


How to replace a heater core on a 94 Lincoln mark8?

The heater box was preassembled and shipped to the Lincoln plant for assembly. The box is installed as a unit then the dashboard is installed...... Get the picture? You have to take the dashboard out and disassemble the heater box to get the job done. I advise a trip to your local library for instructions for your needs first! Not much else to say... Good luck!

Why does the fuse box in my house make a clicking noise when the heater clicks on?

The clicking noise you hear could be the result of the electrical current surging through the fuse box when the heater turns on. It may be a normal sound as the fuse box handles the increased load from the heater. If the clicking noise is accompanied by other issues like power fluctuations or tripped circuits, it's best to have an electrician inspect it for potential problems.

Recently added a third room and wired in ceiling fans for all three rooms and now the AC Water heater breaker will trip about 10 sec after being flipped on?

You should call back the electrician who did the wiring and complain to him. It could indicate incorrect wiring. It could indicate that the electrician put something besides the water heater on the water heater circuit. It could indicate that in the process of remodeling the electrician damaged something. It could be something damaged the circuit leading to the water heater. It could indicate that during the time of the repair, your water heater broke. It could indicate that your circuit breaker is bad. Someone with volt meters needs to be in your house to find the problem.

Can you conect your dryer to a heater circuit?

Not advisable. Both units consume huge amounts of Amps (amperes = current) and the normal 20 or 30 amp breaker may not sustain prolonged operation of both. Where I live, we have two electric meters ... one just for the water heater, the other for the house and all it's electrical needs (except for the water heater).


What circuit breaker is interchangeable with Bryant?

However, some compatible options include Eaton brand circuit breakers, as they may fit in older Bryant panels although it's recommended to consult an electrician for proper guidance and to ensure safety and compatibility.
