However, that connecting branch line is not identified on the proposed new PANEL A. The power conductor from PANEL A to the main house is proposed as a Cu #4 which has an ampacity of 100 amperes. However, the ampacity for the existing house is shown to be an estimated 125 amperes. That exceeds the ampacity of the proposed connecting Cu #4 conductor. Please review and provide a definitive analysis of existing main house power and new guesthouse. The connecting service conductor size to the existing house panel should not be less than the existing panel demand and possibly not less than the total ampacity not used by the secondary guesthouse addition.
