Transfer switch and 110v plug???

In one of the rear bays, along with my 50 amp shore cord, there is an electrical box marked "TRANSFER SWITCH". I found the explanation for the transfer switch in my coach manual, BUT next to the transfer switch is a typical 110v cord with plug just hanging there. Next to that is a 110v receptacle. The plug is at just the right length to be plugged into this receptacle. It is obvious that the intent is for the cord to be plugged into the receptacle sometime. It is hanging loose and has been that way from day one. I searched the manual for an explanation as to when this plug is supposed to be plugged into the receptacle and why. I could find no explanation for this short cord and the receptacle. Why would it just be hanging there? If it were meant to be connected all the time I would assume it would be hard wired. Does anyone know what this cord is for and when it is to be plugged in? I've only had the coach for a month and have found the answer to most things in the manual, but NOT this time. I need help!

I'll bet it's for the engine block heater, but the other Safari owners will know.

As Dirk indicates, on my Winnebago Ultimate that cord goes to the engine block heater, and on my coach the outlet is controlled by a switch inside coach that is marked "Engine Heater." If you have an "Engine Heater" switch somewhere inside, it would be easy to verify that the switch controls that outlet. If you DON'T have an Engine Heater switch somewhere, then you have to plug the cord into the outlet to use the engine heater.

As usual, there will be no charge for the assistance.

I also have this plug in my compartment and it is plugged in. Cant find anything in manuals pertaining to block heaters. I wonder if this plug is for a block heater and if so is it ok to be plugged in all the time? Don't have any switches inside for engine heat.

Just checked again and the plug actually runs from the converter to the outlet. I have a breaker that says block heater ( opt ) so maybe I don't have a block heater.

You mean the PLUG goes to the converter, or the OUTLET is fed from the converter?

And is there actually a breaker in the spot that says "block heater (opt)"?

I think block heaters are wired the way they are so that you can plug them into an extension cord if there's no power available in the coach to run them. If the batteries are dead, for instance.

Wire runs from converter and plugs into the outlet. About the breaker, I just went out to check again and there are more things listed on the label below the breakers then there are breakers and some of the things listed such as central vac and fireplace we do not have. Cant find a plug or outlet anywhere that suggests we have block heater.

Should be easy vsually check the engine block for the heater, I to have the same thing in my electrical compartment, and it was always plugged in, and is really "hot" to the touch if on shore power.

If you have a rear engine cummins, look on the driver side of the block, just below the second exhaust manifold bolt from the tranny, there will be a big round plud on the block with (3) wires going in, thats the block heater.
