The utility grounds that neutral along the road about every 10 pole and at every hydro service because it's so important for safety/reliability to keep it's potential as close as possible to true earth. Reason #2 as it cuts utility power transmission line losses.
Linemen can get shocked by lines that should be dead even when the supply end is open. Current back through the center tap of the transformer secondary induces a voltage on the primary windings back to the utility. Believe it. 2.0V on the secondary is 120V on the primary if 7.2KV to 120/240v.
Generally the closer the linesman is to your dangerous backfeed the more likely he is going to find high voltage. Any minor and otherwise unseen/unknown faults in your service makes it more likely.
Mike M why are you proud of breaking the law and endangering people with something they don't fully understand?
Install a proper transfer switch. They are cheaper than a lawyer and easier/safer for anyone to use.
There are some people the more you explain something. They feel threatened and the tighter they stick to how they partly understand the subject or stay loyal to what they heard their Pappy say on the topic? I'm never right 100% of the time, doubt you are too.
Electrical Code rules are uncommon among government regulations. They actually are there for yours and my safety along with equipment reliability. Much to even my surprise, they make sense when explained how and why.
There is a reason why three prong receptacles, GFI plugs, four wire stove/dryer plugs etc etc etc have been regulated into being. The old ways may have "worked" but they were not safe.
As expensive as electricity is. It's still cheaper and cleaner than running your own powerplant or an engine with line shafts to operate all the machinery.
My relatives and people at parties b*tch at me about the price of power. I have about three different answers.
#1 Sometime when I'm having coffee with the president of the company I'll ask him he can do for you.
#2 Doesn't bother me, like most employees we get a discount.
#3 I just take some electricity home in my lunch box to save on power bills.
