Valterra Mighty Cord 15AF to 30AM Adapter for RV - 12"

The Valterra A10-3015BK Mighty Cord adapter converts a 15 amp female outlet to a 30 amp RV style male connection over a 12 inch cord. It features a 30 amp TT-30 male plug on one end and a 15 amp 5-15R female receptacle on the other, connected by a heavy duty dogbone section.

This style is commonly used as a reverse adapter at RV pedestals, allowing you to plug a household extension cord or 15 amp device into a TT-30 source while giving strain relief and a bit of flexibility.

FAQ

Q: Can I use this to feed my RV panel from a 15 amp cord?
A: No. It is intended to power 15 amp devices from a 30 amp source, not to back feed a coach electrical system.

Q: Why choose a 12 inch dogbone instead of a solid adapter?
A: The flexible section reduces stress on the pedestal outlet and lets the cord hang more naturally than a rigid block adapter.
