Power's Out... No Electrician... No Problem!

ESL’s StormSwitch™ is the ideal solution for portable generator connection. It provides power connectors and a manual transfer switch allowing a quick, safe generator hook-up and operation for any building.

Once installed by a licensed electrician, the StormSwitch™ is so easy and safe to operate that only basic training is required for use. Safety features include an interlocked door and dead-front panel. With ESL’s proprietary mechanism, interlocked molded case switches (or circuit breakers) prevent cross-connecting power sources – Backfeeding the utility grid is unsafe.

The StormSwitch™ is available in 3 models covering the most common power requirements of commercial facilities. ESL’s StormSwitch™ is the safe, economical and flexible solution to ensure your business is ready for any situation requiring portable generator power.
