YES!!
The best way to determine which circuit breaker is for the water heater is with a voltage meter, It is suppose to be only one circuit breaker, but in a faulty application it could be two breakers
There is no way of telling from here. It will be a double breaker, most boxes will have 3 doubles. One for the stove, one for the AC and one for the water heater. Process of elimination should tell you which is for the heater.
NO, it will not damage the vehicle engine by turning the heater ON before the engine has warmed up fully.
A heater may not be keeping a house warm because it is too small for the space. An older heater may not be performing as it should. If you are getting no heat from the heater, you may have blown a fuse and should check the circuit breaker box.
20 amp breaker 12 gauge wire assuming its 120 volt
try higher amp breaker
Yes the wire size is larger for that size breaker but will not effect the 30 amp breaker protection of that circuit.
A 2000 watt heater draws 8.3 amps on a 240 v supply, so the cutout should be set to 10 or 12 amps. <<>> In North America a 2000 watt baseboard heater will be fed with a two pole 15 amp breaker. A two wire cable of #14 copper will be used to connect the supply voltage to the heater.
To answer this question the wattage of the heater is needed.
shut off the power to the box, switch out the breaker and resture the power
There is a thermostat somewhere, usually on the wall or on the heater itself. Just turn the breaker off at the breaker box. Label the breaker if it is not already labeled. Once the power is turned off to the unit, you can disconnect the wires inside the heater to permanantly shut down the unit.
