Below the bluff or up on the hilltop
The hilltop subdivisions are the simpler case. Their panels are newer, and while we still run the load math before promising anything, most of these homes take any of the three setups cleanly: a portable generator with an inlet and interlock, a portable with a manual transfer switch, or a whole-home standby unit with an automatic transfer switch that starts itself.
The historic homes below the bluff need a closer look first. A transfer switch ties into your service equipment, and an older, undersized panel, especially a small 100-amp service in a century-old house, can need upgrading before a standby install is sound. We assess and run the load calculation before quoting, and the panel upgrade cost guide shows what that step adds when a home needs it.
