2022 Tab 400 fuse box--WHERE IS IT?

litchik63 · August 19

I'm pretty sure my husband blew the fuse to the kitchen plugs today. The GFI resetting it doesn't take care of getting the power back on. We are on shore power. Where are the fuses located?

Welcome to the Forums!

The "WFCO" power center is the black box somewhere low along the floor. There is a little "flapper" door that opens by pressing in the top center of the door. Inside, you will find the fuses and circuit breakers for the trailer.

The GFCI circuits would be involved with circuit breakers, not fuses. The first place you should check (if you haven't) is the circuit breaker of the plug the trailer is plugged into. (Your home, or the campground power pole). If the circuit you are plugged into is only a "15 amp" circuit, and you were trying to run several things at a time, you could have tripped that circuit.

So, tell us exactly what you are plugged into. Or, were you trying to make something work with the inverter in the trailer?

We are plugged into our garage. The only thing that doesn't work are the plugs in the trailer. Everything else seems to work.

Not using an inverter.

Just checked and we did not blow the circuit breaker in the house that it is hooked to.

When you open it the layout should be pretty straightforward. Here is what the 2019 400 looks like with door open.

The Kitchen GFI breaker is near the top on mine and is a 15 amp breaker. Typically having 2 appliances on that exceed 1,000 watts each (about 8-9 amp draw each ) will add up to more than 15 amp current and trip the breaker

Thanks Todd. He's now checked the fuses and the circuit breakers. Nothing seems to be blown or wrong. What else could it be? Next steps?

Have you checked the circuit breaker for your shore power source? You may have tripped it in your house, check for lights on your 30 amp plug for shore power and see if the cable is powered.

@litchik63, although you mentioned "The GFI resetting it doesn't take care of getting the power back on," it is not clear if you are referring to the GFCI outlet (and whether you are referring to the trailer kitchen, or the kitchen inside your house.)

I'm not familiar with its exact location in the 400. The below photo is from my 2018 T@B 320 S, but all GFCI outlets are similar, so you should have little problem finding it. Also, you may be plugged into a GFCI protected circuit at your house. The actual GFCI outlet will be located at the beginning of that circuit and is protecting other outlets on the same circuit. You should have one or more in your garage, outside outlets, kitchen, and bath areas (basically, anywhere that water is likely to be present.)

Assuming that the circuit breaker protecting the GFCI outlet has not tripped, the outlet itself may have tripped and just needs to be reset. Locate that outlet (or outlets if there are more than one involved) - - - SEE PHOTO BELOW - - and press the "RESET" button (white button below the red "TEST" button.)

IMPORTANT: A GFCI outlet will not reset unless it has power, so you definitely want to confirm that the GFCI circuit breaker in the trailer power center (as shown in the photo provided by @qhumberd), or your house circuit breaker panel, has not tripped. Even if that breaker appears to not have tripped, flip it "off" and then back "on" to be sure. As also mentioned, if you have too many items drawing power on the circuit, it may be overloaded, so unplug any items on that circuit before resetting the GFCI.

If you have a multimeter, or outlet tester, you can also use one of those to test for power at the outlet. Or, keep it simple, and plug a small appliance into the outlet, like a radio or fan, to see if there is power to the outlet, whether it is the GFCI outlet in your trailer, or the outlet you plugged into at your house.

Good luck!!

Thanks Bayliss, I'll have him reset them even if they look "on".

Bayliss · August 19

@litchik63, I was editing my post when you replied, so if that doesn't work, maybe re-read it to see if there is anything else I mentioned that you may have not seen while I was editing. I hope it works out for you, but I have a pretty good feeling it will.

Turn off the battery switch. Everything except the air conditioner and 120 V outlets will work if the battery switch is on. it may fool you into thinking only your outlets are the problem.

litchik63 · August 19

Thank you all for your help. We are back in business!!

How did you resolve it, @litchik63? Inquiring minds are always interested in how the story ends.

Howdy, Stranger!
