Surge protection can help limit transient overvoltage when correctly selected and installed. It is not a guarantee against all storm damage, a substitute for safe wiring or backup power during an outage.
Know what you want to protect
List sensitive equipment and describe any existing panel-mounted or plug-in surge protection. Ask how a proposed device fits with the home’s electrical system, grounding and existing equipment. Avoid treating a basic power strip as proof of surge protection.
Ask about installation and compatibility
The contractor should explain the device type, panel compatibility, installation location and manufacturer requirements. Request the model number in the proposal so you can review its documentation and understand what its indicator lights mean.
Understand limitations and maintenance
Ask how to recognize a device that needs replacement and what the warranty covers. Protection at the panel and suitable protection at individual devices can serve different roles. Neither keeps appliances running when utility power is lost.

Questions before you book
Does surge protection prevent outages?
No. Surge protection and backup power solve different problems. A surge protective device does not supply electricity when utility power is unavailable.
Does it guarantee protection from lightning?
No. Do not treat any surge device as a guarantee against lightning damage. Ask the installer to explain the product’s limits and warranty.
