The neutral (grounded conductor) cannot be smaller than the required size of the GEC (per table 250.66) and is not required to be larger than the largest ungrounded conductor.
Does neutral wire have to be same size as hot?
The “neutral” wire should ALWAYS be the same size as the “hot” wire. That said, that isn’t alway true either, as there is the case of a 220/120 vac appliance, such as an electric stove/oven. The cord on those will have a smaller neutral.
How do I switch from 100 to 200 amp service?
Can You Change A 100 Amp Panel To 200 Amp? You cannot change a 100 amp panel to a 200 amp panel without upgrading the power service coming into the dwelling. The reason for this is a 200 amp service is much larger in wire size and price than 100 amps.
Can you run a 200 amp sub panel off 200 amp main?
Yes, and you don’t even need another 200A breaker. The 200A breaker alread present in the panel will suffice, and so you can use a subfeed lug kit as DrSparks advises. For that matter, if the main breaker were out at the meter (e.g. a meter-main), you could simply “tee” off it with dual 4/0 to two main-lug panels.
Can you use a 200 amp meter socket for 100 amp service?
NO ! this is a bad idea, even assuming a 200A Breaker would fit, the mains busses in the 100A panel are only sized and rated for 100A, so a 200A Main Breaker would not adequately protect the mains busses of the panel. The Main Breaker, nor any feeder breaker should not exceed the mains (bus) rating.
Does underground electrical wire need to be in conduit?
There’s one restriction: It needs a conduit where the cable is exposed on the outside of the house and to 18 inches below the ground. Burying the cable 24 inches requires more digging, so this method only makes sense if you have easy-to-dig soil or are renting a trench digger.
Does service entrance cable need to be in conduit?
(1) Service-Entrance Cables. So, you’ll either need to have this service-entrance re-run with a conduit, or see if you can get your local electrical inspectors to sign off on using bollards (i.e. concrete-filled metal poles) to protect the meter pan and service cabling as Machavity suggests.

Can you run a 100 amp sub panel off a 200 amp main panel?
Yes that would work. Just make sure to keep your ground and neutral bars separated in the sub panel. Number 8 would be more than sufficient though as far as size goes.
What size wire do I need to run 100 Amp Service 150 feet?
What is the right wire size for 100 Amp service 150 feet distance? You should get 2/0 AWG Copper wire or 4/0 AWG Aluminum wire for single-phase circuits. And, 1/0 AWG Copper wire or 3/0 AWG Aluminum wire if you have three-phase circuits. For these wires, the average voltage drop should be 3%.
