Superior Electric 30A to 50A Locking Adapter

This Superior Electric RVA1510L adapter connects a 30 amp NEMA TT-30P male plug to a 50 amp NEMA SS 2-50R female receptacle. It is built for RV owners and contractors who need to bridge different shore-power standards at campsites or job sites. The locking mechanism helps maintain a secure connection during use.

Black white yellow locking construction

The adapter body uses black white and yellow colour coding for quick visual identification of the circuit. Its straight-blade plug design fits standard inlets while the locking female end resists accidental disconnection from vibration or cable pull. The moulded housing protects internal contacts from weather and rough handling in outdoor environments.

30 amp limit on 50 amp receptacle

The 30 amp male side restricts total draw to 30 amps even though the 50 amp female receptacle can accept higher-rated cords. Users must not exceed the 30 amp supply rating or the upstream breaker will trip. The adapter does not increase available power and is unsuitable for loads that require a genuine 50 amp service.
