What is the size of the conductors supplied from the meter/CT to the Wendy's MDP?

The conductor size from the meter/CT (current transformer) to the main distribution panel (MDP) is crucial for ensuring that it can safely carry the expected electrical load without overheating or causing voltage drop issues. In determining the correct size, considerations such as the total load, distance from the meter to the MDP, and the type of conductors being used play a significant role.

In this case, the choice of 250 KCMIL (thousand circular mils) indicates that the conductors have been specified to handle a substantial current capacity. This particular size strikes a balance between adequate ampacity and practical installation requirements for commercial applications, such as a restaurant chain like Wendy's, where power demands can be relatively high due to kitchen equipment and general operations.

To arrive at this conclusion, it is likely that calculations were based on NEC guidelines, which provide standard ratings for conductors based on their insulation types and environmental conditions. The other sizes, while they could potentially support certain loads, may not be suitable for the specific demands of the installation, or they may represent oversized or undersized options compared to what is warranted in a typical context for a facility of that nature. Thus, the choice of 250 KCMIL reflects the correct application of
