Question: Meter socket

How do I know if a meter socket was evaluated for a top or bottom feed or both?

 

Answer

UL Lists meter sockets under the product category Meter Sockets (PJYZ) located on page 233 in the 2007 UL White Book. This information can also be located using UL’s Online Certification Directory atwww.ul.com/databaseby entering “PJYZ” at the UL Category Code Search. The Guide Information for meter sockets states: “Meter sockets are suitable for supply wiring to enter the enclosure from either the top or the bottom, unless the meter socket is marked ‘Overhead Feed Only’ or ‘Underground Feed Only,’ or the equivalent. The marking ‘Top Feed’ is considered equivalent to ‘Overhead Feed,’ and ‘Bottom Feed’ is considered equivalent to ‘Underground Feed.’”
