Restrictions for Power Mod 1600-2400amp type WT Feed 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 down-stream 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.
