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 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 wire size is required for 312 amps?
Conductor can be loaded to only 80% capacity. 312/ 80% = 390 amp wire is needed for 312 amps. A 500MCM conductor with an insulation factor of 90 degrees C is rated at 395 amps.
What size Teck cable is required for a mini split heat pump that is 15 amps?
Two conductor and three conductor #12 Teck cables are rated at 20 amps. This size is one over from the 15 amp rated wire. This is because on motor loads the conductor size has to be 125% of the motors full load amps. Since all that was stated is 15 amps it is better to err on the larger size wire.
Does a double 30 amp breaker mean you have 60 amps for a 220 outlet?
breakers are rated by wire size, not voltage. the appliance manufacturer will probably specify amperage.
What size wire is for 200 amps?
Service wire required is AWG # 3/0 copper.
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 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 aluminum wire for 100 amps undergroundservice 60 feet from meter?
A 3/0 aluminum conductor will limit the voltage drop to 3% or less when supplying 150 amps for 150 feet on a 240 volt system. This size will allow the conductor to be loaded to 120 amps. 150 x 80% = 120 Conductors are only allowed to be loaded to 80% or their rated capacity. If you need the full 150 amps then you would need to use a wire with a rating of 190 amps. 190 x 80% = 152 amps A 4/0 aluminum conductor will limit the voltage drop to 3% or less when supplying 190 amps for 150 feet on a 240 volt system.
What size wire and breaker for a 240 volt single phase 20 kw electric furnace rated at 83.3 amps?
AWG #3 copper.
What size wire is required for 277 volt fluorescent lighting?
Wire size is governed by amperage not voltage. Voltage is an insulation factor when talking about wire. Add up the amperage of fixtures you want in the circuit. Once that is found then the size of the wire can be calculated.
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
What wire size is required for 312 amps?
Conductor can be loaded to only 80% capacity. 312/ 80% = 390 amp wire is needed for 312 amps. A 500MCM conductor with an insulation factor of 90 degrees C is rated at 395 amps.
What size wire is used for a 220 volt dryer?
For a standard clothes dryer, new homes are roughed in with 3C #10 cable which is rated at 30 amps.
What is the proper size wire cord for a 12 amp vacuum sweeper 120 volt?
16 gauge is rated at 13 amps, but I would use 14 gauge which is rated at 15 amps just to be safe.
What size aluminum wire to feed 125 Amps 220 volt a distance of 175' and what size ground?
A 3/0 aluminum conductor will limit the voltage drop to3% or less when supplying 125 amps for 175 feet on a 220 volt system. If the 125 amp load is a sub distribution panel that is not going to be fully loaded to 125 amps then using the exact connected load, which might be smaller than 125 amps will effect the wire sizing. The grounding conductor for that size distribution panel is #6 bare copper.
