FS/FD™ Metallic Connections
Marine/Industrial Series — 20 and 30 Amp, 250VAC
Mechanically interlocked FS/FD™ Interface receptacle outlets, available
through 30 amp 250VAC, provide added electrical safety in branch circuits.
By design, the plug must be fully inserted into the interlocked receptacle
before the switch or circuit breaker can be turned to the “ON” position,
and the switch or circuit breaker must be in the “OFF” position before the
plug can be withdrawn. This design ensures that when properly installed
and operated, the circuit is made and broken by the switch or circuit
breaker, not by the connectors.

As with all Russellstoll products, mechanically interlocked receptacles
were designed with safety, durability and performance in mind.

unless switch is in “OFF” position
• Circuit breaker protection available on many models
• Ground contacts “make first,” “break last”
