What size amp circuit breaker would protect a 12kW boiler?
The breaker protects the wiring not the boiler. 12,000 watts at 240 volts will require 50 amps. So, you will need a 60 amp breaker using AWG# 6 wire on a dedicated circuit.
Can you use 14 wire for a light off a 20 amp circuit?
Yes, in home wiring as long as it is protected by a 15 amp breaker. Remember this circuit will only handle 1800 watts and cannot be loaded to any more than 1440 watts. So if each light is 75 watts then the maximum you can install is 19.
What size amp circuit breaker do you use on a 55 watt fluorescent light?
A 55 watt fluorescent light only pulls 0.4 amps. Lights can be installed on a 15 amp breaker using 14/2 wire. A maximum of 1440 watts is all that is allowed on a 15 amp circuit.
Can you upgrade a 15 Amps circuit breaker for a 40 Amp for a 8.5 Watt shower?
Not unless you change the wiring for that circuit. The breaker protects the wiring and if you install a 40 amp breaker on a 15 amp wire circuit you will have a fire in your home.
How many 1.2 amp lights can a 20 amp breaker hold?
No more than 13 maximum on a 20 amp circuit.
How many watts can be put on a 20 amp 208 volt circuit breaker?
A 20 amp circuit breaker at 208 volts can handle up to 4160 watts (20 amps x 208 volts = 4160 watts). This is calculated by multiplying the amperage by the voltage to determine the maximum wattage capacity of the circuit.
How many watts can a 20 amp breaker handle per hour?
A 20 amp breaker can handle up to 2400 watts per hour (20 amps x 120 volts = 2400 watts).
If you have a 30 amp breaker how many watts can it use?
To answer this question a voltage must be given. Watts = Amps x Volts. <<>> Answer At 115 volts ac, 30 amps equals 3,450 watts.
What size amp circuit breaker would protect a 12kW boiler?
The breaker protects the wiring not the boiler. 12,000 watts at 240 volts will require 50 amps. So, you will need a 60 amp breaker using AWG# 6 wire on a dedicated circuit.
If a 120 volt current is protected by a 25 amp circuit breaker What is the largest number of watts an appliance can safely use?
The largest number of watts an appliance can safely use on a 120V circuit protected by a 25A breaker is 3000 watts. You calculate this by multiplying the voltage (120V) by the amperage (25A). This gives you a maximum power capacity of 3000 watts on this circuit.
How many light cans can a circuit hold?
you just have to do some math. if the can lights are the only thing on the circuit then times the wattage of each bulb by the total bulbs and only put 80% of the circuit breaker max on the line. ie 20 amp breaker and 120 volt power equals 2400 watts max. 80% of that is 1920 watts. 15 amp breaker and 120 volt power equal 1800 watts max. 80% of that is 1440 watts. if there are already other item on the circuit then you should test the line fully loaded with an amp clamp to see what its carrying already, and then deduct that from your totals
Can you use 14 wire for a light off a 20 amp circuit?
Yes, in home wiring as long as it is protected by a 15 amp breaker. Remember this circuit will only handle 1800 watts and cannot be loaded to any more than 1440 watts. So if each light is 75 watts then the maximum you can install is 19.
New shop 20 amp circuit 32 amp fixture how many fixtures can be put on circuit?
A 32 amp fixture can not be fed from a 20 amp breaker as the breaker will trip every time.
Why will too many electrical devices operating at one time after blow a fuse or trip a circuit breaker?
The load exceeds the limit of the breaker or fuse. For example a 20 amp breaker on a 120 volt circuit will handle 2400 watts. Exceed that wattage and the breaker will trip or the fuse will blow.
What size circuit breaker is needed for a 300 watt bulb?
A 300 watt bulb requires a circuit breaker of at least 2.5 amps. This can be determined by dividing the power (300 watts) by the voltage (120 volts). However, considering normal breaker sizes, a 5 amp breaker would be sufficient for a 300 watt bulb.
How many watts can be on a 15amp breaker?
At 120 volts a 15 amp breaker can be loaded to 1800 watts before it will trip. If it is a continuous load then the electrical code states that it is only allowed to be loaded to 80%. This will be 1800 x .8 = 1440 watts. If the voltage is not 120 volts use the following equation Watts = Amps x Volts. Amps being the breaker size that is to be used.
How many watts can you run in 20 amp?
20 Amp * 120 Volts = 2400 Watts 2400 Watt * 80% max use = 1920 Watts planned normal usage for a circuit with a 20 Amp breaker.
