Neautral wire overheating
A while back the neutral wire coming OUT of my EMS-HW30C surge protector was over heating. On 2 separate occasions I cut/cleaned the wire and secured as tight as i could in the terminal. Now the neutr...

It's unlikely hat the EMS is causing the problem. Properly done screw connections offer no more resistance than any other point in the system. I would go back and double check everything you did before the problem started. My guess is that the extra length of extension cords is causing the problem, or that possibly the additional cord is made with the wrong size wire. All 30A cable has to be 10g a, even the neutral. A shore power cord over 100' should be a size larger.
You are going to have to start eliminating components until you find what is causing it. Remove the EMS, you are going to have to anyway to repair or replace it. Reconnect the wires and use a clamp on meter to measure currents. Turn off all of the AC breakers and begin turning them on one at a time and see if you have an appliance or device that is drawing excessive current. Do the same thing with and without the new extension cord. it sounds like a complicated process, but it's simply eliminating one potential problem at a time. You may need to enlist the help of an electrical savvy person to do this.
Somewhere you are going to find a neutral wire that is undersized or a high resistance connectionand causing to much current to be drawn.
