Whole house surge protectors panel-mount surge protective devices for homes
A whole house surge protector mounts at or in the main electrical panel and limits voltage spikes from the utility, lightning-induced surges and switching events before they reach appliances, HVAC and electronics. StormForge supplies panel-mount surge protective devices (SPDs) to electrical distributors, installers and private label brands.
- Panel-mount SPDs for single, split-phase and 3-phase panels
- Type 1 / Type 2 installation formats (by model)
- LED status indicators; replaceable modules on some models
- Private label housings, labels and manuals
How a whole house surge protector works
Inside the device, metal-oxide varistors (MOVs) or similar components stay inactive at normal voltage and conduct when voltage spikes, diverting surge current to ground. Installed at the service panel, the protector covers every circuit downstream. Point-of-use surge strips remain useful for sensitive electronics — the two are complementary.
Formats we quote
- Type 1 format — installed on the line side of the main breaker or at the meter (by model and local code)
- Type 2 format — installed on the load side, typically on a dedicated breaker in the panel; the most common residential choice
- Breaker-style or DIN-rail modules for specific panels and international markets
- Combination units adding coax and telephone/data line protection
Classification and installation location depend on your market’s electrical code; specify it on the RFQ.
What to specify
System voltage and configuration (120/240 V split-phase, 230 V single-phase, 3-phase), installation format, target surge current class, indicator and alarm options, enclosure rating requirements, labeling and packaging. Lightning arresters for service entrances and antennas are covered on the lightning arrester page.
Ratings and compliance, honestly
Surge current, voltage protection rating and similar figures are model-specific. We do not claim UL, ETL, CSA, CE, IEC or other listings or ratings by default; devices are built to the standards you specify and test reports available for a given model can be provided on request. Installation must be done by a licensed electrician.

Frequently asked questions
Is a whole house surge protector worth adding to a storm-protection range?
Outages and lightning-season surges hit the same regions as hurricanes and severe storms, so it is a natural add-on for electrical and hardware distributors.
Type 1 or Type 2 — which should we stock?
Type 2 panel-mount devices are the most common residential choice; Type 1 formats suit line-side installation where local code allows. Specify your market and we quote both.
Do you supply 230 V and 3-phase models?
Yes, by model; state voltage, phase and installation format on the RFQ.
Can we put our own brand on the device?
Yes, labels, housing color and packaging can be private label.
Are your surge protectors and lightning arresters UL listed or IEC tested?
We do not claim UL, ETL, CSA, CE, IEC or any other listing, certification, rating or test result by default. Devices are built to the standards you specify on the RFQ, and test reports available for a given model can be provided on request. Installation must be done by a licensed electrician to local code.
