For a 100 amp panel, a #4 copper or #2 aluminum conductor would typically be used as a neutral conductor. It's important to consult local electrical codes or a licensed electrician to ensure compliance with regulations and safety standards.
The neutral is the same size as the feeder conductors for a 200 amp service.

How do you ground a 100 amp service panel?
In the service distribution panel there are termination points at the top of the panel. Two of the utilities "hot" conductors terminate on the main breaker. The neutral utility termination point is on a terminal block usually off to the side near the main hot terminations. It is in this neutral termination block where the system ground connects from the ground rods to the distribution panel. For a 100 amp panel the wire size will be a #6 bare copper conductor.
Can you tap off of a 200 amp service for 2 100 amp panels?
Yes, but at every reduction in wire size there has to be a breaker sized to the smaller wire size. The wire size for 100 amp panels is recommended at #3 copper conductor. From the 200 amp feeder panel you will require a 100 amp two pole breaker for each of the two 100 amp services. Keep in mind that if you run the 100 amp services close to maximum this will take away the capacity of the 200 amp service for other branch circuits coming off of it. Also keep in mind that if the panels are located, not in the same building as the 200 amp service that the 100 amp panels will be treated as separate services and will have to be constructed like a 100 amp service. This includes ground rods. Also the bonding screw will have to be removed that connects the neutral buss to the panel enclosure.
What is the largest sub panel you can install off from a 60 amp main panel fed by 100 amp service?
You can install a 100 amp sub panel off a 60 amp main panel fed by 100 amp service. This allows for the sub panel to be adequately powered with headroom for future circuits or expansions. It is important to ensure the wire size from the main panel to the sub panel is sufficient to handle the load.
What amp fuse do you use for a 100 watt bulb?
Fuses or breakers are used to protect the conductor to the load. A #14 wire conductor is rated for 15 amps. Most home circuitry is done with #14 wire. The minimum size breaker in an electrical panel is 15 amp so it looks like a 15 amp fuse or breaker can be used for a 100 watt light bulb.
What size aluminum ser cable needed for 100 amp sub panel?
For a 100 amp sub panel, you would typically need a 2-2-2-4 aluminum SER cable. This cable consists of three insulated conductors (two hot and one neutral) and one bare ground wire. It is important to always consult your local electrical code and a qualified electrician to ensure you have the correct size and type of cable for your specific installation.

What wire size do you need for a 125 amp panel with a 100 amp main breaker?
A #3 copper conductor with an insulation factor of 90 degrees C is rated at 115 amps. Even though the panel is rated at a higher amperage it is the main breaker that governs the wire size.
What size breaker do you use for a 100 amp sub panel?
A 100-A sub-panel would be fed from a 100-A breaker.
What re size for a 220 volt 100 amp panel distance d 100 feet?
A #1 copper or 1/0 aluminium conductor will limit the voltage drop to 3% or less when supplying 100 amps for 100 feet on a 240 volt a single phase system.

Yes, but at every reduction in wire size there has to be a breaker sized to the smaller wire size. The wire size for 100 amp panels is recommended at #3 copper conductor.

What is the recommended ground wire size for a 100 amp sub panel installation?
The recommended ground wire size for a 100 amp sub panel installation is typically 8 copper wire.
What size grounding conductor is needed for a 80 amp service?
For service sizes of 100 amps and less a #8 bare copper conductor is required.

What size ground wire for 100a service?
A 100 amp residential service requires a size #8 copper wire, it should be insulated in green.
What size wire should be used for a 100 amp panel?
For a 100 amp panel, a wire size of at least 3 AWG copper or 1/0 AWG aluminum should be used to ensure proper electrical capacity and safety.
What size aluminum ser cable needed for 100 amp sub panel?
For a 100 amp sub panel, you would typically need a 2-2-2-4 aluminum SER cable. This cable consists of three insulated conductors (two hot and one neutral) and one bare ground wire.
