Panel grounding wire

Hey Guys,


Should separate grounding wires be connected to each panel when there are 2 electric panel boxes with separate feeder cables from the meter?

Both panel boxes were 200a with a 200a main breaker with 3 conductor feeder cables from the meter.

I indicated in my report that each panel requires a grounding wire because only the panel on the right had a separate copper wiring grounding to a copper water pipe.

Best regards,

Yes, two grounds are needed, with one to each panel. They can have a common source. Typically, a distribution trough may be found between the meter and panels. Here are some photos of a similar setup. 400 amps to 2 - 200A panels…

Joe,


Thanks for the consultation. Your pictures of the dual panel boxes are what I inspected. The only difference was the left sidi box did not have a grounding wire attached.

Best regards,

Climbing Mt Everest to get to that pesky 2nd air handler

What do you mean the windows are defective! They open far enough...

Yes, folks, a real house. Realtor had to make the beds and pick food up off the floor before she dared show this dog to any prospective buyers. No, I didn't inspect the air handlers. I excluded them from the scope of the inspection.

Biggest problem in this house was the casement windows. When the genius who stucco'd the house put the drip guards above the windows, he never bothered to check clearances. ALL windows in the home only opened about 1-2 inches maximum. Ya think there was an emergency egress problem, boys and girls?!!! Oh well...

Great pick up on the windows Joe, I have come across this before with the installation of aluminum awnings. BTW, we are now off topic.
