Rough wiring for the River House is approaching completion. Pictured above is where the automatic transfer switch and main breaker panel will reside within my shop. In total the house will have one main and 4 sub-panels; one in the primary mechanical room, one in the secondary mechanical room, one in the laundry, and one in the garage. The cost for multiple panels is far outweighed by the savings for shorter copper runs within the house. The automatic transfer switch will allow our battery backup system to kick in during a loss of power to the house and to time shift our use of electricity. During off-peak hours the batteries will charge and during peak hours will be used to power the house. Concord is switching to time-of-use metering so this capability should allow us to significantly reduce our electrical energy costs.
