Environment:
NF panelboard interior

Cause:
application and product features

Resolution:
The bus ampere rating is 250A . The ampere break down is 125A and anything over 125A will be 250A.  Anything over 250A will use a 400A bus.  The UL label will indicate the maximum ampere
rating of the panel which in this case will be 250A. However, if the panel in the field was manufactured by the plant, it will be UL listed and marked based on ampere rating designated at the time of order.
