What size wire and breaker you need for metal halide 400w bulb?

The size of wire and breaker sizing are based on the current of the circuit. To answer this question a voltage must be stated or look on the ballast for the amperage and add that to the question.


When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?

When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.


What size circuit breaker should be used if you use 5 horsepower of air-conditioning?

To answer this question a voltage value must be given. Circuit breakers protect the conductors that feed the load. The lower the voltage value, the higher the current value, hence a larger the wire size is needed and therefore larger the breaker size for the circuit. In reverse the higher the voltage value, the lower the current value, hence a smaller the wire size can be used therefore smaller the breaker size for the circuit.


Installing a 120volt appliance what breaker is needed at the electric box?

Need to know what the wattage or the amperage is of the appliance. The load amperage is what governs the wire size and the breaker to protect the circuit.


What size amp circuit breaker should be used for a home entertainment system?

You use the correct size breaker depending on the size wire in the circuit. If the circuit is wired with AWG #12 wire use a 20 amp breaker. If it is wired with AWG #14 wire then use a 15 amp breaker.


How are Branch circuit protected?

Branch circuits are protected by the circuit breaker found in the electrical panel. Each circuit should have its one breaker. The breaker should be rated to protect the insulation of the wire, so you can determine the breaker size based on the circuit conductor size Example #14-2 should be protected by a 15 amp breaker


What is the standard to select circuit breaker?

Add up your amps to calculate your breaker size. Add up your loads (amps), divide by 0.8, and choose that size breaker. If that number does not correspond to a standard size breaker you go to the next higher standard size breaker.


Is the main circuit breaker is a sum of the sub circuit breaker?

Typically yes because that is what makes sense. However, the subpanel could have the same size breaker as long as the panel were rated for that amperage and the wire sizes were appropriate.


What is the smallest size circuit breaker found in the normal home?

The biggest circuit breaker in any home is the main breaker located in your main breaker panel that is installed where your electrical service cable comes into your home.


What size amp circuit breaker should be used for 110 outlet?

The size breaker you use is determined by the size wire used in the circuit. If you use AWG #12/2 wire then use a 20 amp breaker. If you use AWG # 14/2 then use a 15 amp breaker.


What size amp circuit breaker should be used for a pool light?

The pool light is usually on a 15 amp circuit. The breaker feeding this circuit must have a GFCI rating.


What size breaker for?
