Apartment Breaker & Load Analysis
Budget: $15 – $25 USD
I have an existing electrical riser where each apartment is fed with 6 AWG conductors. Every unit falls in the 500–700 sq ft range and is outfitted with the usual kitchen package—range, refrigerator, dishwasher, microwave—as well as Central heating and cooling systems.
Before I commit to new tenant improvements, I need a professional load study that tells me two things:
• the largest breaker size that can safely be installed at the electric room and servicing the apartment panel given the 6 AWG feeder, and
• the realistic maximum panel demand, factoring in the appliances listed above plus general lighting and receptacle loads for a space of this size, and
• analysis of what breaker size could be installed if the feeder wires were 4 AWG
Please base your calculations on the current NEC, reference the tables you use, and call out any derating, diversity or demand factors you apply. A concise PDF report and the underlying spreadsheet (Excel or similar) will be ideal so I can forward them to the local AHJ if needed.
