MEP-803A hookup question

[blhar15]

I have a MEP-803A generator and trying to figure out how to wire the military pigtail to the lugs, which wire goes where. I know it depends on the configuration you want. I am looking for a single phase 110V. I believe the pigtail has a black, white, red, blue and green wires.

Thanks

If you lower the front of the control panel (where all the gauges are) you will see the voltage selection switch. On it shows the various wiring configurations (with the terminal information about how to wire). Have you looked at this? Do you have a copy of the manual for this generator? The wiring is discussed in it as well. Do realize that once you select the appropriate voltage and phase of your desire, you will also need to change the setting of the ammeter on the gauge panel to match the lug output (Do not change this setting while running!). Good luck and stay safe doing anything with wiring.

There should be a schematic on the drivers side door inside.

Dont forget to read the -10 manual. It has it all!

Thanks for the feedback

Make sure you choose the correct method of grounding your genes depending on whether you are connected to an existing structure's power system or are using the machine in a stand alone power system.

Yes, it only takes one time being hooked to electricity, and not being able to move, or do anything other then KNOW, "Am I screwed now". And I have rode that horse twice, thank you.

Which side is the driver's side? Are these generators left hand drive or right hand drive? Or did they switch depending on which country they were exported to?

Facing the control panel it would be the door to the left. As it would sit on a trailer control panel toward the rear.

An easier way to think of it, is the control panel is always the rear of the set. There are several Power Plants with two gen sets on it, and they are positioned longways, and sideways, so if you always think of the control panel being the rear of the set, you're always right.

I appreciate all the responses, but still need to clear up a couple of things. I do have the manual and I saw the info on the inside of the door. What I am still unclear on is what color wires go to which terminals? I am using a 5 wire pigtail that will be plugged in to a military distribution box. I have attached a few photos.

Thanks

That distribution box is for 3 phase and you will probably be using single phase. Make a simple break out box on a 4 wire cable so you can have 120/240 single phase with a ground.

A simple way to figure out how an military cable gets hooked up is this. Look at the cable head pins. They are marked A,B,C,D and sometimes E.

Pin A is L-1
Pin B is L-2
Pin C is L-3
Pin D is N
and if I have to tell you where the fifth gets hooked up at, you should NOT be doing this!
Use an ohm meter to find what cable goes to what pin.
If I remember right, and I haven't look in a good number of years, if you look directly into the cable head, the pin to the right of the keyway, is A. BUT check it!
Do you have the TM for your D-Box?

If you are doing a single phase connection it will be a 4-wire setup. Using industry standard color codes your two load wires will be black and red. The blue will only be used for 3-phase 5-wire setups. White is neutral and green/bare is ground.
