Cummins

This is Portlandia Electric Supply's complete genuine Cummins catalog — over 500 SKUs spanning Cummins Power Generation equipment from the generator itself to the smallest service part. The collection covers four categories. Standby generators: Cummins RS-series liquid-cooled units for homes and light commercial buildings, engineered around Cummins' own engines and backed by the deepest service network in the industry. Automatic transfer switches: the OTEC line from 125A to 600A in single-phase and three-phase, 120/208V and 277/480V configurations, plus RA-series switches for residential service entrance.

Accessories and controls: genuine Cummins battery chargers (6A and 10A), extreme cold weather kits for RS22 through RS100 units, coolant heaters, sound-attenuated enclosure upgrades from Sound Level 1 to Level 2, remote display panels and annunciators (HMI112 through HMI320), base barriers, battery trays, and the control kits that integrate Cummins generators into monitored systems.

Factory extended warranties: coverage up to 10 years or 5,000 hours across C20D6 through C100D6C generator sets, in parts-only, parts-and-labor, and parts-labor-travel tiers — bought with the generator or added to qualifying units. Every part here is genuine Cummins with correct part numbers (A030Y976 through the A06-series), so fitment is never a guess.
