Surge Protective Device (SPD)
Model: G0074090
120/240 VAC Single Split-Phase
Description
Lightning strikes and utility switching can cause voltage transients and power
surges in the electrical grid. These surges travel through distribution lines
and into homes or businesses, damaging sensitive electronic appliances and
shortening their life. Many transients go undetected, but overtime, contribute
to sudden and inexplicable failures of electrical equipment. Products that are
susceptible to damage include: mobile phones, computers, televisions,
appliances, smart home devices, and lighting fixtures.
Generac’s whole-house surge protection device (SPD) helps protect against
these damaging surges and transients by blocking them from entering homes or
businesses. It has thermally protected metal oxide varistors (MOVs) that help
reduce risk of thermal damage. Its compact, weather-resistant design offers
installation flexibility.
Generac SPDs may be installed:
- Indoors or Outdoors
- Within a Distribution Panel on the Load Side of a 20 amp Breaker
