Protecting More Than One Building
A detached shop, barn or guest house fed from the house usually has its own subpanel. A protector at the main panel limits surges coming in on the service; a second one at the subpanel protects the equipment in that building. Each panel is priced in the written quote.
Fort Worth Is on the 2026 NEC
Fort Worth adopted the 2026 National Electrical Code effective September 1, 2026 (City of Fort Worth). Under Section 230.67, in the NEC since 2020, a dwelling's service needs a Type 1 or Type 2 surge-protective device, integral to or immediately adjacent to the service equipment, rated at least 10kA nominal discharge current, and the rule applies when service equipment is replaced (Leviton). So any Fort Worth panel replacement includes one.
Type 1 or Type 2?
Under UL 1449, a Type 1 device is intended for the line side of the service disconnect, as far as the meter socket enclosure, and a Type 2 device for the load side of the main breaker, at the panel (Hubbell, UL 1449 summary). Either meets 230.67. Most homes get a Type 2 unit on a breaker in the main panel. Prices and the full comparison are in whole-home surge protector cost.
Storms
Spring and summer storms bring lightning to North Texas, and the National Weather Service warns that lightning can reach the inside of a house through its wiring. A whole-house protector helps with surges on the lines; it cannot promise protection from a direct strike.
Frequently Asked Questions
$350–$850 installed for a standard unit at the main panel: about $350–$650 for 80kA and $550–$850 for 120kA. Additional protectors at subpanels are priced in the same written quote.
Yes. If the building has its own subpanel, a protector there covers its equipment. If it is fed without one, we will tell you what it would take.
Sometimes. Most units have status lights; if the indicator shows the protection is spent after a storm, the unit or its module has to be replaced.
No. Surge protectors handle short spikes. Flickering usually points to a loose connection or a utility voltage problem, which is a troubleshooting call; the diagnostic starts at $240 and is credited to the repair.
