ASCO Series 300 Manual Transfer Switch with Integrated Quick-Connects (MTQ)

The ASCO Series 300 Manual Transfer Switch with Integrated Quick-Connects (MTQ) provides a means for quickly connecting a portable or temporary generator to a building’s electrical system to provide backup power, or to provide a “backup to the backup” when servicing an off-line engine-generator. The Series 300 Manual Transfer Switch with Integrated Quick Connects provides a total temporary power connection and transfer solution that provides a complete UL 1008-listed solution in a single unit.

At facilities where backup power must be available, even when servicing a facility’s sole generator, National Electrical Code® Article 700.3(F) requires that a permanent switching means be provided to connect an interim source of secondary power. For facilities without a permanent backup generator, an MTS and a connecting means can facilitate the connection of a temporary or portable generator when needed, without the cost of a
permanent engine-generator.
