Manufacturer description
The MECMO TT-30P to 3X 5-15R/5-20R RV distribution adapter turns one 30 amp RV or generator receptacle into three standard household outlets. Plug the 3-prong NEMA TT-30P male end into a TT-30 campground pedestal or generator outlet, and you get three lighted T-blade sockets that accept both 15 amp and 20 amp household plugs. The cord is rated for 30A at 125V, or 3,750 watts total. That covers power tools, work lights and small appliances running side by side, as long as their combined draw stays under the ceiling. Each outlet is a 5-15R/5-20R T-blade connector. An LED on the outlet end…

Frequently Asked Questions
Can I use this to plug my RV into a regular house outlet?
No. The adapter has a TT-30P male plug and three household female outlets. It takes power from a 30 amp RV receptacle or generator and feeds standard household plugs. It does not work in the other direction.
How much can I run off all three outlets at the same time?
The adapter is rated 30A at 125V, which is 3,750 watts total. That limit is shared across all three outlets, so keep the combined draw of everything plugged in under 3,750W.
Will my 20 amp plugs fit these outlets?
Yes. Each of the three outlets is a NEMA 5-15R/5-20R T-blade connector, so it takes both standard 15 amp plugs and 20 amp plugs with the sideways neutral blade.
Does it work with a portable generator?
It works with any generator that has a NEMA TT-30R (30 amp, 125V RV-style) receptacle. It will not fit 50 amp RV outlets or 240V twist-lock generator outlets.
How long is the cord, and can it be used outdoors?
The cord is about 1 foot long. It uses 3-conductor 10 AWG STW cable rated for indoor and outdoor use, with a UV-resistant, flame-retardant molded plug.
