The Firman L5-30P to TT-30R Adapter Adds a Travel Trailer Ready TT-30R Outlet to Your Firman Generator

The Firman 1605 is an adapter with an L5-30P plug on one end and a Travel Trailer Ready TT-30R outlet on the other. It adds another outlet to your Firman generator and is rated for 3750W of output.

It's for RV owners who want to plug the RV into a Firman generator and get on to the next trip. The adapter carries cETL certification.


Firman L5-30P to TT-30R Adapter Features

Travel Trailer Ready TT-30R Outlet

The TT-30R end is Travel Trailer Ready, so you can plug your RV into your Firman generator through the adapter.

L5-30P Plug

The L5-30P plug end connects to the generator, which adds another outlet to its control panel.

3750W Output

Firman rates the 1605 for 3750W, so you know the limit before you connect your load.

Safe, Secure and Easy to Use

Firman designed the adapter to add an outlet safely and securely, and it's easy and convenient to use.

cETL Certified

The 1605 carries cETL certification.


Real-World Applications

RV camping. Plug the RV into your Firman generator at the campsite.

Travel trailers. Connect a travel trailer cord to the generator through the TT-30R end.

Extra outlet options. Add another outlet type to the generator's control panel.


Practical Comparison

Firman 1605 Versus the Firman 1610 Adapter

The 1610 works the other way, with a TT-30P plug and an L5-30R outlet, and it's also rated for 3750W. Choose the 1605 when you're plugging into an L5-30 outlet and need a TT-30R outlet for your RV.

Firman 1605 Versus Plugging the RV In Directly

An RV cord with a TT-30P plug needs a TT-30R outlet. If your generator's connection is an L5-30 outlet instead, the 1605 provides the TT-30R.


Buyer Guidance

Check Your Generator's Outlet

The adapter's plug is an L5-30P, so your generator needs an outlet that accepts it. The other end is a TT-30R outlet for your RV's cord.

Keep Loads Within 3750W

Firman rates the adapter for 3750W. Keep the RV's load within that rating and within what your generator can supply.

This May Be A Good Fit If

  • Your Firman generator has an outlet that accepts an L5-30P plug
  • Your RV or travel trailer connects with a TT-30 plug
  • Your load stays within 3750W
  • You want a cETL certified adapter
