Restrictions for 1600-2400amp type WT Power Mod Pull-Thru Tap Boxes:
Type WT feed thru tap boxes cannot be used as service equipment. The feed thru conductors must have
upstream circuit protection. When fed by a Class L fuse, there are restrictions on the use of additional downstream
horizontal cross-bus connected WTBN, WET, or WT type Power Mod tap boxes. When another tap box
is connected to the same meter-bank, a type WXB module must be used as protection for the downstream tap
box (placed between the incoming WT tap box and the downstream outgoing tap box). This restriction does
NOT apply if the tap box is fed from a Siemens Sentron or VL series molded case circuit breaker. Note that the
maximum amperage for a Siemens Sentron circuit breaker is 2,000A. Please note that Siemens type WL circuit
breakers CANNOT be used to feed WT Power Mod tap boxes.
