Furrion FP52GEN4-SB
50A female to 30A four-prong male. For an installation using the specified 50A female and 30A four-prong male pattern.
Furrion RV Pigtail Adapters: 30A vs 50A Connector Guide
A short RV shore-power pigtail is useful only when both ends match the outlet and RV inlet exactly. These three Furrion adapters have different male and female connector arrangements. Before ordering, compare the manufacturer's MPN, physical blade pattern, rated voltage and circuit protection.
Identify both ends, not just the amperage
FP52GEN4-SB: A Furrion 50A-female to 30A four-prong-male pigtail. It is not the same connector configuration as a TT-30 straight-blade adapter.
FP31GEN4R-SB: A separate 30A-female to 30A four-prong-male pigtail. Check the four-prong source pattern and the RV-side mating connection before choosing it.
FP5030R-SB: A 30A TT-30P straight-blade plug to SS2-50R 50A twist-lock female connector. The 50A-rated connector does not increase the available 30A supply capacity.
Electrical safety: Do not assume that all 30A plugs have identical voltage or blade arrangements. Only mate the exact approved connector patterns. The power source, breaker, cord, adapter and RV inlet must all be suitable for the intended system. An adapter cannot supply missing voltage legs or increase power availability.

Connection indicators and handling
These Furrion adapter listings describe ergonomic grips or pull handles intended to make disconnection easier. The product information also identifies connection-status indication features; compare the exact model's current instruction sheet to understand the indicators before relying on them for troubleshooting. Indicator lights do not replace testing by qualified electrical personnel when a supply fault is suspected.

Furrion FP31GEN4R-SB
30A female to 30A four-prong male. For the matching 30A female and four-prong male connection family.
Furrion FP5030R-SB
TT-30P straight-blade to SS2-50R twist-lock. For a 30A straight-blade source and a matching 50A twist-lock inlet; available supply remains limited by its breaker.
Before connecting at a campsite or generator
Switch off the applicable supply before making or breaking connections. Inspect both mating contacts for heat damage, discoloration or looseness. Confirm the shore-power or generator receptacle's NEMA designation, nominal voltage and breaker rating; never force an adapter into a different receptacle. Manage RV loads to the actual available supply.

Common questions
Can I draw 50A through FP5030R-SB on a 30A source?
No. The shore power source remains limited to its actual rated and protected capacity.
Are all 30A 4-prong connections the same as TT-30?
No. Compare the exact four-prong pattern to the TT-30 straight-blade configuration; matching the amperage label alone is insufficient.
Do these pigtails replace a damaged RV inlet?
No. A damaged or overheated inlet needs the correct replacement and inspection of the electrical connection.
