You pull into a campsite at dusk, find the pedestal by the picnic table, and the plug on the end of your shore cord does not match the outlet staring back at you. RV power plug types are the handful of plug shapes that connect an RV to shore power, and the wrong shape means no power for the night. This guide walks through the plug types in the listings, what each one fits, and the adapters that join them.

RV power plug types
The adapters here use 4 plug shapes. The NEMA TT-30P is the 30 amp RV plug that fits a campground pedestal, with a round ground pin and flat blades set at an angle. The NEMA 5-15P is the 15 amp household plug found on a garage or house outlet. The NEMA L5-30R is a 30 amp twist lock receptacle: the plug turns and locks so it cannot pull loose. Household outlets also come in a 5-20R shape, which takes a 20 amp plug as well as a 15 amp plug, and the LBSC splitter (on Amazon) offers three of those sockets.
| Plug | Amps | Where it fits | Amazon |
|---|---|---|---|
| NEMA TT-30P | 30 amp | RV pedestal | |
| NEMA 5-15P | 15 amp | Household outlet | |
| NEMA L5-30R | 30 amp | Twist lock RV inlet | |
| NEMA 5-20R | 20 amp | Household outlet |
How the adapters in this guide work
Direction is the whole question. The LBSC adapter starts at a 30 amp pedestal and splits into three household outlets, so it feeds tools, a mini-fridge or chargers from one RV outlet. The POWGRN, RVGUARD and Kohree adapters (on Amazon) run the other way: they plug into a 15 amp household outlet and feed a 30 amp RV inlet, so the RV can charge batteries and run low-power appliances at home. The Kohree end is a twist lock, while the POWGRN and RVGUARD ends are TT-30R, so match the female end to the inlet on the trailer.
A few details help at the pedestal after dark. An LED indicator shows live power at a glance, and the LBSC, RVGUARD and Kohree adapters list one. Grip handles help pull a stiff plug free, and the POWGRN cord lists grip handles on the ends while the RVGUARD cord lists a disconnect handle. Cold weather stiffens cords, and the POWGRN listing states weather resistance down to -40°C.
Match the amps on both ends
The adapters here state their figures, and the figure on the household side sets the limit. The POWGRN, RVGUARD and Kohree cords are 125V and 1875W on 10 gauge or 10/3 gauge wire, with a 15 amp plug on the household end and a 30 amp receptacle on the RV end. The LBSC splitter is 120V and 20 amp max across its three outlets, with thickened copper wiring and a casing that withstands up to 125°C/257°F. Check the figures on the adapter before plugging in a load, and keep the load inside the lowest figure in the chain. The LBSC splitter is the only adapter here that adds outlets; the other 3 are cords that change the plug shape without adding outlets. See the 30 amp vs 50 amp RV power cord guide for the larger cord sizes.

The 4 adapters below cover the plug shapes above: one splitter that turns a 30 amp pedestal into household outlets, and 3 cords that join a household outlet to a 30 amp RV inlet.

FAQ: power away from the grid
What is a TT-30 plug?
A TT-30 plug is the 30 amp RV plug that fits a campground pedestal. The LBSC adapter starts with a TT-30P male plug, and the POWGRN and RVGUARD cords end in a TT-30R female receptacle, so the TT-30 shape is the RV side of every adapter here except the Kohree twist lock.
Can I plug a 30 amp RV into a household outlet?
Yes, with an adapter cord. The POWGRN, RVGUARD and Kohree cords join a 15 amp household plug to a 30 amp RV inlet, and the RVGUARD listing states the cord keeps batteries charged during storage. The household side stays at 15 amps, so run low-power appliances and keep the load inside the figures on the cord.
What does the LED indicator show?
The LED shows live power. The LBSC splitter, the RVGUARD cord and the Kohree cord list an LED power indicator, and the Kohree LED glows green when there is power. If the LED stays dark, the pedestal or household outlet has no power at that moment.
Do I need a twist lock adapter?
Only if the trailer inlet is a twist lock. The Kohree adapter ends in an L5-30R twist lock receptacle with a threaded ring, while the POWGRN and RVGUARD cords end in a TT-30R receptacle. Match the female end to the inlet on the trailer before buying. See the best L5-30 generator adapter for RV for more twist lock options.
