Re: [RE-wrenches] neutral sizing for sense

Drake, I believe that is for a single phase 2 wire output only. I am assuming one hot and one neutral for the inverter output in this case. I would think most *grid tied* inverters fall under 705.95B, where the neutral is only a voltage sense and can be sized as small as the equipment ground.

Re: [RE-wrenches] neutral sizing for sense

"the maximum load connected between the neutral and any one ungrounded [10] conductor plus the inverter [9] output rating shall not exceed the ampacity [5] of the neutral conductor [6]." So the neutral conductor is supposed to be sized for the connected load plus the entire maximum output of

Re: [RE-wrenches] Neutral sizing

I have a long triplex wire run with a smaller neutral to my place from the utility entrance, and I do end up with a large load on one leg often. When another large load is on the other leg to balance the legs, it reduces the voltage drop dramatically. The voltage on the one leg rises when I

Re: [RE-wrenches] Neutral sizing

HI Drake and all, Thanks for this. As I understand this better now, maybe. Neutral sizing changes between supply side and load side of main service panel. Others have chimed in with an argument that can be made that if the neutral wire is sized for a 200 amp service then it should be OK even

...@glbcc.com;RE-wrenches;Cc: Subject:Re: [RE-wrenches] Neutral sizing Hi Jay, Is this for an inverted output circuit? If so then I think the NEC reference you’re looking for is 705.95(B). That says you can size the neutral to the same size as the EGC if the neutral is used only for instrumentation
