About this item

  • Easily mounted to flat surfaces
  • Safe and reliable performance
  • Fits in compact areas
  • Input Voltage: 120/240 VAC, 60 Hz


The T-30 can be installed on the back of a WFCO 8900 Series Power center or, like the T-57, can be easily mounted to any flat surface. The compact design allows for placement in areas with limited space. Both transfer switches are engineered for safe and reliable performance.

Installed for a skoolie conversion where I wanted to eliminate the possibility of me burning out my inverter while hooked up to shore power. It was easy to install and works exactly as it should. I’m usually running off batteries/inverter so hooked it up reverse to the directions. That way batteries are the default power and I have no delay powering up. When I hook to shore power there is a short delay before it cuts power from inverter and switches over. This is a great unit and I would get one again without hesitation.

Better than the original equipment switch with more substantial lugs for wires.

took about a hour to replace the old transfer box, because of it's location! But it was just about a perfect match on wire locations.

These wires do not look like the same thickness as the one in the photo.This is a Fire hazard how's this even allowed to be sold!Good thing I looked at this thing and checked, the wires looked Way too thin to me, and I was right!This is only rated for 30 amps with the internal wires used.And I'm just outside my window overturn, I didn't check this thing sooner!If the seller cares to send me another unit with 6 gauge wiring I will gladly return this one and leave a positive review if this happens to be a one-off mistake.Not happy, now I have to buy a different oneIf you bought this already, please check inside your RV the gauge of the wires inside!It's basically half the size of the wires what they're supposed to be this is ridiculous!By the way this is my first negative review after tens of thousands of dollars on Amazon LOL

This unit was super easy to install. Completed a 50A upgrade in a Northwood Desert Fox 05. The easiest part of the whole job. Everything is well marked on terminal board and direction sheet to connect right up.

Replaced my burned out transfer switch with this one. All connections were one for one, and it works great, no humming like some do.
