Its purpose driven design helps keep the generator outside the living area, which can reduce the likelihood of fumes entering the home while you stay comfortable inside. The enclosure combines rugged steel construction with a durable powder coat, delivering weather resistance while maintaining a clean appearance in a yard or garage exterior. Thoughtful engineering puts accessibility first, so technicians can reach wiring through a removable front face and work within generous interior space. With a history of practical reliability, Reliance Controls offers long standing experience in power transfer gear that you can count on in everyday use.\u003c\/p\u003e\n\u003ch2\u003eWhat it does\u003c\/h2\u003e\n\u003cp\u003eThis non metallic enclosure offers a watertight connection to your transfer switch or panel, while a powder coated steel body stands up to weather and wear.

It is sized for generators up to 12 500 running watts and is built to tolerate outdoor conditions whether in rain, sun, or humidity.
