Mr Z

Just wanted to throw it out there and double check. Thanks Billy Bob, and I'll have to see about cost, but I like your ideas on isolating the electronics. The lawnmower breakage didn't cross my mind, and that would put a major hole in the plan I had. Thank you much for your input.

Short answer...YES! Longer answer...the ground rods are there mostly for powerful surges, such as lightning. They don't provide a reliable path for lower voltages. The main safety reason that the grounding gets connected to the grounded conductor back to the utility is to provide a good path to clear ground faults. Without that bonding at the service a ground fault/short might not trip the breaker. OK, but the neutral would be connected to the ground rods, it would have it's own, and quite separately so would the bare conductors from the house. But, that would not be sufficient in the case of a ground fault?

Basically what I was going to do with the new panel is have all my bare conductors on the proper bus, and bonded to ground rods outside. And, I was going to put all the neutrals (white) on their respective buss, and drive ground rods for them as well. Maybe a little overkill, but I have a shop with a tablesaw, compressor, and other motor loads, and I'd rather not have any wired connection of the ground and neutral if possible. They would both be grounded to earth, just not bonded to the other in the panel.

That is, must you connect the busses in the panel, if you run ground rods to both the neutral bus, and the grounding buss independent of eachother?

250.24. Grounding Services (A) Grounding Neutral. Alternating-current services that are supplied from a grounded electrical system from the utility must have the grounded (neutral) conductor connected to a grounding electrode of the specified in 250.52 in accordance with Part III or Article 250 in accordance with (1) though (5). See 250.24©. This clearly states that the neutral of the service must be connected to earth ground. Does it state anywhere that this connection MUST be made in the panel, or can you have separate grounding rods for each buss, neutral and ground? Due to the electronics in the house, I would rather the neutral and grounding conductors were as separate as possible.
