MEP oo3a lug question

[Mark H.]

Hello everyone, again I would like to take the time to thank everone here on the board that has helped me in the past.
Well I have another question in the form of what order do you hook into the lug box for 120v single phase, 120-240v single phase, and then the three phase order. I dont know which lugs to hook my neutral ect. the directions did not seem super clear to me. I will be looking forward to hear from you guys again. Thank You, Mark

Mark- I also use a MEP-003A for my backup power. I have been well pleased with them. We were hit hard by Ivan and Katrina here in Alabama thus making a backup generator very important. I keep a spare 003A as a backup to my main 003A just in case.
On the lug connections, there is a diagram on the cover of the enclosure of the 4 lugs which explain the hookup. If its not clear enough,just reply back and I'll look at mine to refresh my memory and will answer back.

Hi John,

Thankyou, for responding it does not seem super clear to me which order to hook into the lugs if you could check yours and let me know I would greatly app. it. Thankyou, Mark H.

Mark- When I connected the wires to my 120/240 single phase breaker box: L1 went to top left connection of main breaker, L3 went to top right connection of main breaker and
L0 went to neutral strip. This makes L1 and L0= 120v., L3 and L0= 120v., and L1 and L3= 240v. Be sure to rotate the RECONNECTION SWITCH on the generator lug box fully clockwise to the 120/240 1 phase before starting generator. Use a good multimeter to check voltage before applying power to a load. Remember, this thing is powerful enough to kill you. Good luck John
