Why Seguin Homeowners Are Upgrading Their Panels
Seguin has a lot of housing built in the 1950s through 1970s. A meaningful portion of it still runs on the original 100-amp panel. That was fine for the electrical load of the era. It is not fine for a home running central AC, an EV charger, a home office, and a hot tub.
Many of those homes are also on panels made by Federal Pacific or Zinsco — both documented to fail to trip under overload. "It works fine" is not a panel safety assessment. Insurance carriers are increasingly refusing to renew coverage on homes with FPE panels. Justin finds one or two a year in Seguin. He explains what it is, gives a flat-rate replacement quote, and doesn't push. Most people replace it.
Signs Your Panel Needs Replacement
- Breakers trip frequently under normal household load
- Lights flicker or dim when the HVAC kicks on
- Burning smell or warmth near the electrical panel
- Fuse box instead of circuit breakers — needs full conversion
- Panel is under 100 amps
- Adding an EV charger, hot tub, or major appliance
- Insurance carrier won't renew your homeowner's policy
- Home remodel or addition requiring new circuits
