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

No, a breaker needs to be loaded less than 80 percent. As they reach their tripping point they get hot. The circuit rating, breaker and wiring is not designed for 21 amps. The next size would be a 25 to 30 amp breaker that has #10 wire feeding it.

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).


Every time you vacuum you blow the breaker in your house can you change the breaker?

How is an electric heater hot water heater turned on?

An electric water heater is typically turned on by locating the power switch on the unit or on the circuit breaker panel, then flipping the switch to the "on" position. Some heaters may also have a temperature control setting that needs to be adjusted to activate the heating element. Always follow the manufacturer's instructions when operating an electric water heater.

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.


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.
