Model: G0074090

Type: Installation guide

Generac G0074090 is a whole-house surge protection device (SPD) designed to safeguard your home or business from damaging voltage transients and power surges. With a surge current capacity of 50kA per phase and a short circuit current rating of 200kA, it offers robust protection against lightning strikes and utility switching. The SPD is suitable for both indoor and outdoor installations and can be mounted within a distribution panel on the load side of a 20 amp breaker. Its compact size and weather-resistant NEMA 4X enclosure provide installation flexibility and durability.

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, appli-

ances, 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
