Whole-Home Surge & Lightning Protection in Casselberry

No device can promise that. A whole-home surge protective device (SPD) at the panel limits surges that come in on the power lines from nearby lightning and utility switching, which are far more common than direct strikes. Protecting the building itself from a direct strike is the job of a lightning protection system with air terminals and grounding, installed by a lightning protection specialist. Surges can also enter through cable, satellite and phone lines, which need their own protection.

Some Florida utilities have offered surge programs with a device installed at the meter for a monthly fee. Terms, coverage and availability change, so check with your utility directly. A panel-mounted device installed by an electrician is a one-time purchase that you own. Some homeowners use both. Compare what each one covers, what it costs over several years and who pays if equipment is damaged.

Yes, for sensitive electronics. A whole-home device reduces large surges, and a good point-of-use protector at computers, TVs and networking equipment adds a second layer close to the equipment. Replace plug-in strips after a major surge or when their protection indicator goes out, because their protective parts wear out over time.
