I scanned the UL White Book and did not find a category listing for bolt-in or plug-in type watt-hour meters. There are several categories for the meter sockets. If UL hasn't taken it on, I can't imagine that anyone has paid any other NRTL to evaluate equipment that typically doesn't require a listing. I have heard of AHJ's waiving the listing requirements for equipment when no standard exists... I would suggest to the AHJ that there is no listing for watt-hour meters so this requirement is impossible to meet.

He wanted to see the "UL Listing" on the meter. I called Austin International (our vendor) about the meter in question (Itron Centron C1S) and they said that UL doest test meters as they (normally) are not used on the customer side of the service. Is there another listing for meters that would satisfy a nit-picky inspector? To make matters worse, we now have in stock both Itron Centron C1S meters as well as Schlumberger Centron C1S meters. Did Schlumberger buy out Itron? Or vice versa? Any help on the main panel calculation and acceptable listings for meter would be greatly appreciated. Peter T.
