What size service cable do I need for a 200 amp service?

What size service cable do I need for a 200 amp service?

Wiring 200 amp service requires either #2/0 copper wiring or #4/0 aluminum or aluminum clad wiring. Which wire used is determined by the voltage drop and length of the wiring. Many electrical contractors opt to use #4/0 aluminum or copper-clad wire.

How do you calculate voltage drop over distance?

To calculate voltage drop:

1. Multiply current in amperes by the length of the circuit in feet to get ampere-feet. Circuit length is the distance from the point of origin to the load end of the circuit.
2. Divide by 100.
3. Multiply by proper voltage drop value in tables. Result is voltage drop.

Is 200 amp service per leg?

In the US, a 200 amp service will provide 200 amps per leg. You get a two pole 200A circuit breaker with such a service with 120 volts between each leg and neutral and 240 volts between legs.

How much does it cost to get a 200 amp service?

The national average for an upgrade to 200-amp service ranges from $3,500 to $4,500.

How much does a 200 amp service cost?

The costs of installing a 200 amp service is not cheap. You will be spending anywhere from $1,500 to $3,000 for a 2,600 square foot home. The cost will depend on the type of wire you use, whether it be copper or aluminum. We suggest using copper or copper-clad aluminum if your house has a large load capacity.

What kind of wire do I need for a 200 amp service?

For copper wiring with a 200 amp service, you will need to use #4 AWG copper wire. AWG stands for American wire gage, which is the standard for wire gage in the US. The next option for a 200 amp service, is aluminum, or copper-clad aluminum.

How big of a wire do I need for 70 amp?

For a 70 amp, the safest wire size is a gauge 3. For 80 amp, the safest wire size is gauge 2. The rule of thumb for 100 amp is that you go with a wire size gauge 1. 125 amp requires a wire size 2/0. For 150 amp, the right wire size is 3/0.

How big should wire gauge for 1000ft service run?

Want to run wire 1000 feet under ground from pole to house. Will be using 100 amp service single phase. Would like to know what size gauge of wire should I use. 1000 feet underground, split phase 120/240V service, 3 wires, this is the main service to the house (so we get a favorable 83% derate on NEC 310.15b7, so calculating for 83 amps).

The costs of installing a 200 amp service is not cheap. You will be spending anywhere from $1,500 to $3,000 for a 2,600 square foot home. The cost will depend on the type of wire you use, whether it be copper or aluminum. We suggest using copper or copper-clad aluminum if your house has a large load capacity.

How big of wire do I need for a 200 amp service?

It is a 200 amp service. This is going to be burried most likely in conduit and none of it will be indoors and will probably be THHN aluminum. I am not sure what size wire to use. I was told that according to electrical code, a 200 amp service can’t be loaded beyond 80%.

When to use 179 amps for voltage drop?

When a electrical contractor wires your house they are suppose to do a load calculation of your home to determine the size of service for your home. If the load calculation comes up to 179 amps and you have a 200 amp service, then the 179 amps is what you would use in you voltage drop calculation.

How do you calculate service drop in a house?

To calculate service drop you will have to know the load amps of your house or what ever it is your running the 200 amp service too. Just because you have a 100, 150,175,200, 400 amp service doesn’t mean that’s how much your load is. So this is kind of tricky.
