Hello I have a regular 3 wire 120/240 system.
Whilst looking at the service drop and breaker box I noticed the neutral wire seems very small. It is definitely smaller than the two main conductors..
I know the neutral is allowed to be smaller or at least was when the service was installed but it seems too small. Especially considering there is a 30amp outlet for an RV connected the box.
My question is can the neutral be LARGER than the conductors.. for example 1/0 if they are 2/0.
I don't know their sizes but I have some THHN wire that is 1/0
Would make quick work to have an electrician come hook it up and hard to overcharge me for 30 mins of work with me supplying the materials
