Information that changes the scope

  • The existing service size and panel condition
  • Which circuits are grounded and which are original
  • The planned year-round heating, water, and appliance loads
  • Whether the property is on a well and how the pump is fed
  • Exposure, moisture, and where exterior equipment sits

A service upgrade is decided by a calculated load, not by the number of empty breaker spaces. Adding equipment consumes capacity whether or not a slot is free.

What a camp needs for year-round electrical use

  • A former seasonal camp used or renovated for year-round living
  • An undersized service, often 60-amp, that cannot carry modern heating and appliances
  • Ungrounded or two-wire circuits behind updated finishes
  • Adding a heat pump, water heater, or well-pump load to a seasonal system
  • A lakeshore property with moisture, exposure, or freeze concerns

What a clear estimate should address

The written scope should separate the service and panel resize from any branch-circuit rewiring, name who coordinates the utility and permit, and account for freeze protection and the well pump if present. A camp conversion is usually a capacity project first and a repair second.

Safety boundary

A seasonal building that has sat unheated or been added to piecemeal can hide conditions that are not visible. Do not assume a circuit is safe for a new continuous load just because it powered a summer appliance.
