Which Size Box?

摘要

An electrician asked me a very interesting question concerning the sizing of a junction or pull box and the difference between the two. They are basically the same. Electricians use junction and pull boxes as access points for pulling and feeding conductors through raceway systems. In many installations, use of boxes is necessary, or there would be a greater number of offsets, saddles and bends between outlets or fittings than are permitted per the National Electrical Code (NEC).
