I have a storage building that has 100-amp service into it, panel has 100-amp main breaker. I am building another building about 100 ft. away. The first building has a window ac unit (120V) and two 60-watt bulbs, all of which are only used occasionally. I need a minimum of 60 amps in the second building. Would it be ok to put a 100-amp breaker in the main panel and put a 100-amp panel in the second one? Do I need to pull three wires and put in ground rods for the second building or pull four wires and use existing ground? Also what size wire should I run?

Comment below about general ineffectiveness of ground rods is basically correct. But they are better than nothing and in unusual circumstances may be all that is available. On that basis, they are well worth installing.

You will be happiest with the utility running a 100amp service from the utility transformer to your new shed. Run a bare #6 ground wire in the entire length of the trench. No building ever had too good of a ground system. If you pony panel than a 60amp breaker in the exisiting service and #6 or larger copper will be required to the new shed. You could be getting into some VD problems with length of run from the utility transformer. Use a panel from Reliance Controls. They have a generator transfer switch built right in. This is the time to install it, or someday wish you had.

It is less than 50' from the transformer to the first panel. I need a minimum of 60 amps in the second building, that is why I ask about pulling 100 in to it. In case I need more in the future. I do understand the importance of a good grounding system for safety.

"No building ever had too good of a ground system." Thats the honest truth.
My parents live in southern Maine and I guess is really hard to get a good ground in their ground conditions. Apparently about the only ground you can ever count on is the water main which is tough if you've not on city water.

I"ve come to the conclusion that the only "good" ground is back at the service entrance from the utility company. Ground rods are only good for lightning protection and can never be relied on to protect you from a "short" in equipment or wiring.

Brian you may want someone else to do your electrical work in the future. What do you base your conclusion on?

One simple rod can electrify the earth around it causing eletrocution hazards if there is no other path for fault current to travel.Dont insult the guy about his electrical work.

In the NEC it states that ground rods are only supplementary grounding.Maybe Brian read his codebook.NEC 65 bucks in Barnes and Noble,buy one and read about rods yourself.

For some real good help in interpreting and understanding the NEC, I recommend Mike Holt's site. His writings on "Grounding vs Bonding" made a believer out of me.

Thats the series of articles Ive been folling in a magazine.11 parts entitled Grounding vs Bonding by Mike Holt.The same guy that writes or publishes "Changes to the NEC" book every code period.Even then there is still siome contradictions in certain areas.Alot of confusion in the subject.Many electrical systems will work without it being done properly,which goes unnoticed untill somebody gets shocked or killed of that system.When in doubt go for overkill and protect yourself and others.The recent news from the Boy Scout jamboree may remind us how common electrocution is,although that was no fault of bad grounding.Never did find out the voltage in that tragedy.I would guess maybe 4160.It was a military base.When ones body is electrified with high[medium] voltage anyone else who touches them in an attemp to save them most always also gets electrocuted.Once every 19 days someone is killed by 277 volts.Most common killer is 110 volts,not 277.

What do you base your statement on? As I understand it, the NEC requires that the neutral and ground be separate in an outbuilding that is fed from a main panel in another building. This means 3 wires plus a ground for 220 service. Is that not correct?
