[RE-wrenches] PV GEC to the same point as the utility service GEC?

Wrenches, Questions: Does the PV GEC have to be bonded to the ground electrode system at the same point as the utility service equipment GEC? Is there a code section to back this up? Additional info: 1. The DC side of the inverter is a separately derived system and therefore needs a GE

Re: [RE-wrenches] useful info on wire color coding

My 2 cents on this issue which I have encountered on numerous occasions. Here in NYC the majority of service switch installs agree with the convention of BLACK, RED, BLUE. However, I have seen a few older service switches with the reverse, BLUE, RED, BLACK. The only documented place I have ever

Usually the building steel is bonded to the water main or in some cases a ground conductor ring is installed under the foundation and bonded to the base of all the building steel columns.

Re: [RE-wrenches] MC Cable for DC runs

Howie, I've looked at a few different MC cable manufacturer data sheets and I can't find a distinction between AC or DC. In general I wouldn't expect there to be a difference since AC RMS voltage and current ratings are sort of a 'DC equivalent'. But the only way to be sure is contact a cable m

Re: [RE-wrenches] Sunny Island Battery Disconnects

Hi William, I don't have a lot of experience with battery OCPD, but I did have a project where we used a Square D heavy duty safety switch to protect a negative grounded 600VDC battery string. All of the heavy duty switches are AC and DC rated (H363, H364, H365...). For DC applications, go her
