I ordered a Cutler Hammer 400 amp twin meter, the box had obviously been opened before I got it(since the staples weren't secured)anyway upon opening the meter base I discovered the utility side didn't have lugs for the linemen to connect to. I called my vendor and he ordered me the lugs for it(at my cost), he said they are sold separately. I have some issues with the fact that 1. I have never had to install lugs before on a meter base and find this peculiar. 2. He said the lugs came with phillip screws...how can I possibly torque these enough that there won't be any vibrations on a 400 amp bus/lug? Am I being too worrisome, because I have seen what happened on a 200 amp service that had a bolt from the main breaker(from the factory) to the bus which got glowing red because it was a turn and a half lose. Whats your guys thoughts?
