Generator Sizing, Done on Paper.
Monmouth County, NJ.
Monmouth County Generac performs written load calculations for Monmouth County homeowners before any generator is quoted, because the two classic mistakes in this business are selling a unit too small to start the well pump and selling a unit two sizes bigger than the house will ever draw. Both are avoidable with an hour of arithmetic.
How real sizing works
We walk the house and the panel. Every circuit that matters gets listed with its running load and, for motors, its startup surge: air conditioners, well pumps, sump pumps, refrigeration, heat system blowers. Startup surge is the number that breaks naive sizing, because a compressor that runs at 15 amps can demand triple that for the second it starts, and two compressors starting together is how an undersized unit faults on transfer. The calculation stacks the realistic worst case, applies load management where it saves you money, and lands on a kilowatt number with engineering behind it.
The Monmouth County load profile
Sizing here has local fingerprints. Well pumps rule the western townships and demand hard surge headroom. Shore homes stack dehumidifiers and sump pumps that must never shed. The county’s larger homes increasingly carry EV chargers, which are trivially manageable loads if the plan accounts for them and a nasty surprise if it does not. Natural gas heat keeps winter electrical loads modest; heat pump conversions flip that math entirely. Your house has one of these profiles, and the right generator follows from it.
Free with any quote, valuable even without one
The load calculation comes free with any installation estimate, and the worksheet is yours either way. Bring us a competitor’s quote and we will happily check its sizing math against your actual panel; catching an undersized proposal before contract is a cheaper fix than a change order after the pad is poured. An honest number travels well.
