depends on length of circuit, continuous duty or not. not knowing these factors i would say 12awg on a 20a breaker.

What size wire is required for a 220 volt at 54 amps?
6 AWG
What size of wire you need for a 42 amps heater?
8 AWG.
What size wire and breaker do you need for a 5000 watt garage heater?
Look on the heater and see what amps it is pulling. That will determine the wire size and breaker size. It must be on a dedicated circuit. 15 amps = AWG # 14 wire with 15 amp breaker 20 amps = AWG # 12 wire with 20 amp breaker 30 amps = AWG # 10 wire with 30 amp breaker 40 amps = AWG # 8 wire with 40 amp breaker
What wire size is used for 100 watt 12 volt lamp?
Volts * Amps = Watts 12 V * ?Amps = 100 Watts OR ? Amps =100W/12V OR 8.33 Amps = 100W/12V Use a 10Amp fuse inline and you can get by with 16Ga wire.
What size breaker needs to be installed for 15000 watt 240 volt heater?
15,000 watts at 240 volts will use 62.5 amps. Therefore you will need to use AWG #3 wire on a 100 amp breaker.
What wire size 240 volt 21 amps 150 foot run?
A #10 copper conductor will limit the voltage drop to 3% or less when supplying 21 amps for 150 feet on a 240 volt system.
What wire size in a 20 amp 250 volt circuit?
The wire rating for a # 12 wire is 20 amps. If you are going to continuously load the circuit you need to de-rate the wire by 80%. This brings the current down to 20 x .8 = 16 amps. The wire rating of a # 10 wire is 30 amps. 30 x .8 = 24 amps.
What size amp circuit breaker should be used for a 20 gallon 1500 watts water heater?
To answer this question the voltage that is to be used should be stated. If the tank is 240 volts then 1500/240 = 6.25 amps. A 2 pole 15 amp breaker with a #14 wire will work fine. If the working voltage is 120 volts then 1500/120 =12.5 amps. A single pole 20 amp breaker with a #12 conductor will work fine. The reason for the up size in wire for the 120 volt system is that conductors are only allowed to be loaded to 80% capacity. A #14 wire is rated at 15 amps x 80% = 12 amps which is just under the required amperage of the 1500 watt heater. A #12 wire is rated at 20 amps x 80% = 16 amps. The code book states that if the current of the load is over the capacity of the wire rating the next size conductor is to be used.
What size amp breaker you need for a ac and a heater unit?
The sizing of a breaker is dependant upon the size of the wire it protects. The size of the wire is dependant upon what the load current in amps is. Without the amperage and wattage and the voltage of the appliances an answer can not be given. W = A x V, Amps = Watts/ Volts.
How do you connect a 240 volt electric heater It is a baseboard unit the has a black and red internal wire for connection Do you use 12 2 wire or 12 3 wire The thermostat has 2 red 2 black wire?
2 wire (plus ground) is all you need for a 240 volt heater provided there is no 120 volt accessories in the heater such as a built in convenience receptacle. If cable is used, the white wire of the 2 wire cable will be a HOT-LEG even though it is white-this is one of the code exceptions. The size of the guage is dependent on the size of the load and other factors. 12 guage will handle up to 1500 watts generally.
What size wire and breaker for a 240 volt single phase 20 kw electric furnace rated at 83.3 amps?
AWG #3 copper.
Fuse size for 7.5 HP 3 Phase 440 Volt Motor?
The electrical code states that a 7.5 HP 460 volt three phase motor draws 11 amps. For fuse sizes, non time delay - 30 amps, time delay type D - 20 amps and if using a breaker it will be 30 amps. Minimum wire size is #12 and the maximum setting of overload devices will be 13.75 amps
