Connects a 50-amp RV power cord to a 30-amp campground pedestal outlet. 12" dogbone style with finger grip handle on the male end for easy insertion and removal. Heavy-duty cable designed for outdoor use. RV still limited to 30 amps when using this adapter.
50-amp RVs are increasingly common — large motorhomes, fifth wheels, and dual-air-conditioner travel trailers are almost universally built with 50-amp NEMA 14-50 power inlets. But 30-amp service is still standard at many campgrounds, state parks, and older RV parks. When a 50-amp RV pulls into a campsite with only 30-amp pedestals, the A10-3050FHVP is the adapter that bridges the gap.
The A10-3050FHVP is a 12" dogbone-style adapter cord — the male NEMA TT-30P plug inserts into the campground's 30-amp outlet, and the female NEMA 14-50R receptacle accepts the RV's 50-amp power cord. The "FH" suffix denotes the finger grip handle molded onto the male end, which makes insertion and especially extraction from a campground pedestal significantly easier — particularly when the pedestal is wet, cold, or at an awkward angle. Heavy-duty cable construction is designed for the outdoor use conditions typical of campground hookups. Part of Valterra's trusted Mighty Cord RV power accessory line.

Red color makes the adapter easy to spot in your storage compartment and at the pedestal — less likely to be left behind at the campsite
This adapter allows your 50-amp RV power cord to connect physically to a 30-amp campground outlet — but the available power is limited to what the 30-amp circuit can supply. Using this adapter does not give your 50-amp RV access to 50-amp power. What this means in practice: • Your RV's total power draw must stay within 30 amps (approximately 3,600 watts at 120V) at all times • 50-amp RVs on 30-amp service receive only a single 120V leg — not the 240V dual-phase service the RV is designed for • Running both air conditioners simultaneously, or the air conditioner with the microwave and electric water heater, will typically trip the 30-amp breaker • With careful load management — running one AC at a time, avoiding simultaneous high-draw appliances — most RV functions can be used on 30-amp service This is the most common adapter an RV owner carries — 30-amp sites are abundant and 50-amp RVs camping at them is an everyday scenario. Just manage your loads accordingly.
Valterra's adapter part numbers encode key features in the suffix: A10 — Mighty Cord power adapter family 3050 — 30 amp male to 50 amp female F — Finger grip handle on male end H — Handle (reinforces the grip feature) VP — Vinyl packaged / carded retail package Without the "FH" suffix (e.g. A10-3050VP), the adapter is the same 30A-to-50A dogbone but without the finger grip handle on the male end. The finger grip is the key upgrade on this model — worth it for frequent connection and disconnection at campground pedestals.
Connecting Your 50A RV to a 30-Amp Campsite: 1. Confirm 30-Amp Service: Locate the 30-amp outlet on the campground pedestal (NEMA TT-30R — round slot with a T-shaped slot and a ground hole) 2. Plug Male End into Pedestal: Using the finger grip handle, insert the NEMA TT-30P male plug into the 30-amp outlet on the pedestal 3. Connect RV Power Cord: Plug your RV's 50-amp power cord into the adapter's NEMA 14-50R female receptacle 4. Turn On Pedestal Power: Flip the pedestal breaker to the on position 5. Manage Your Load: With 30 amps and single-phase 120V available, avoid running both air conditioners simultaneously or combining other high-draw appliances 6. Disconnecting: Turn off the pedestal breaker first, then use the finger grip handle to pull the male plug free Always turn off the pedestal breaker before connecting or disconnecting to prevent arcing.
