SB 50A CONN #6 RED (Yale YT17-1721-APP)

A damaged SB 50A connector can interrupt electrical continuity in a power circuit. This aftermarket replacement part references the Yale catalog and carries the cross-reference number YT17-1721-APP. The connector is a heavy-duty, single-pole device rated for 50 amperes. Its plain mechanical function is to join a #6 AWG cable to a mating receptacle. A concrete failure consequence is that a corroded or melted connector can cause intermittent power loss or a complete open circuit. Keeping the connector in sound condition helps maintain reliable current flow under load. Verify the serial number or application, then call (562) 693-7748.
