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.
Check Chandler’s current requirements
Chandler Building Safety publishes its adopted codes and permit guidance. Ask the contractor to check the current requirements for your address and scope, rather than relying on an old online checklist. Exterior equipment may also involve separate association requirements.
A proposal for an EV charger should identify the equipment, wiring route, permit responsibility and any wall repair. Compare those items before comparing the total price.
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.
Compare the scope of your quote
- Device and panel compatibility
- Installation location and access
- Any related electrical corrections
- Equipment warranty and replacement requirements
A contractor sets the price after reviewing the actual work. Ask about assessment fees, exclusions and approval of changes before booking. Compare proposals using the same scope.
Questions about whole-home surge protection
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.
