for 300 feet for 100 amp rated service I would use Aluminum direct burial 1/0-1/0-1/0-1/0, the forth can be as low as #4 for the ground (but also in conduit, even if in conduit must still be rated underground wire and required by code also) Also note the size wire the breaker can handle, cannot cut strands to make fit, …
Thereof, What size wire do I need for a 100 amp service?
You need a 3-3-3-5 copper SER cable to carry 100 amps (that’s three #3 gauge for the two hot wires and the neutral and a #5 gauge for the ground).
Also to know is, What size service entrance cable do I need for a 200 amp service?
Subsequently, question is, How do I calculate what size wire I need? – Amps = Watts divided by volts.
– Feet = One-way wire distance.
– % Volt Drop = Percentage of voltage drop acceptable for this circuit (typically 2% to 5%)
Also, What size copper wire do I need for 100 amp service?
2-gauge
Can mobile home feeder be run in conduit?
If it’s individual USE it can be used as long as it’s in conduit where it emerges from the ground all the way through to where it enters the MH panel.
What size wire do I need for a 100 amp breaker?
The cable must have a wire gauge sufficient to the amperage of the subpanel—a 100-amp subpanel requires #4 copper wires, for example.
Will #2 wire fit in a 100 amp breaker?
Sub Panels When it comes to the lines connecting master and secondary panels, where the line will carry as much as a full 100 amps, use a 2-gauge non-metallic sheathed electrical cable. … Each wire should be 2-gauge in size.
Is mobile home Feeder direct burial?
Want to see other Direct Burial cables? … Aluminum Mobile Home Feeder cable is designed for mobile homes as a service entrance cable. The cable is sunlight resistant and is approved for use in accordance with the recommendations of the National Electric Code in raceways and underground installations.
Can you run NMWU in conduit?
NMWU cable in conduit – one continuous cable running from the panelboard in the house to a junction box, first device box or panel installed in the garage. The cable is protected by PVC conduit on all exterior surfaces and for the entire underground section.
What size wire do I need for a 200 foot run?
8 gauge wire to 30 amp circuit.
What wire size do I need to go 100 feet for a 60 amp service to a workshop?
My rule of thumb for a service connection is to use the largest conductors that will fit. If 6 AWG fits, then use it, but 8 AWG would work. I know, it’s only a 100 foot run, but your workshop may eventually grow to have more power loads, so a larger service conductor provides a better power factor (cooler wires).
What size wire do I need for 100 amps?
The cable must have a wire gauge sufficient to the amperage of the subpanel—a 100-amp subpanel requires #4 copper wires, for example.
How do I know what size wire I need?
To calculate the gauge of stranded wire, you’ll need to double the diameter. So, if you’ve measured a wire’s diameter to be 0.005 inches (0.127 mm), multiply this value by itself. The result will be 0.000025 in (0.000635 mm). Multiply the result by the number of strands in the wire.
What is a feeder cable?
Feeder cables are used to supply power from one part of a facility to another, from point A to point B. Perfect for providing temporary power service during construction or to supply power to specialized equipment. Primary feeder cables typically run between main switchboards and power distribution transformers.
What wire should I use for underground?
THWN-2 wire, for example, is a standard type for running through underground conduit. Use thick-walled conduit at least 3/4 inch in diameter for this application. Never use thin-wall EMT conduit for underground applications. Running wire through Schedule 40 PVC conduit.
What size wire do I need for a 50 amp sub panel?
Check what size cable you will need for the amperage chosen and the length. For example, 6-3G cable is designed for 50 amps when the length of wire does not exceed 55 feet. Beyond that length, a thicker wire is required, due to the voltage drop.
