Neutral wire burning in surge protector

It needs a new connector but you could try to pigtail with some #8 solid.

I always worry about getting every strand under the clamp. I ended up using #8 stranded from the EMS to the panel. Solid #10 hits the input.

Can't find it by the foot anymore :(

I agree, loose terminals cause heat. There are proper specs for tightening heavy gauge terminals. I use the VERY tight spec :)

I had a 125a breaker popping at my house caused buy a loose connection on 1/0 cable. Tightening it fixed the problem.

Any idea if progressive would replace the surge protector under the lifetime warranty? or would this type of damage some how void the warranty?

Thanks for the replies, I considered that, but I'm just wondering why this happened twice in a short period of time. The first time a friend who is a qualified electrician cleaned and reconnected the wire. He screwed it on very tight. I also live in this camper, so it's running 24/7. Would a high energy draw cause the neutral to over heat? The appliances i keep plugged in are the Fridge, Microwave, 2 lamps, 1 fan, flat screen TV, computer, computer speakers, toaster oven, toaster, and my wife's Hair straightener on top of the trailers AC unit. My surge protector currently reads 122v 3a 60h.

The only answer is a poor connection. Period. Heat spreads from the poor connection. You may have screwed down the screw perfectly, but the connection below that may be poor, and with no insulation to melt, you won't know what is hot.

Get an infrared laser pistol shaped thermometer and point it around the connection, you will find the hot spot easily with one of those, and then know what you have to fix.

I bought one for only $30 on sale, and I use it to check my tires when running, my brakes and calipers, and all around my house to find where the cold comes in and the heat is hottest.

Ouch. It looks like one of those events has taken a bite out of the sensor that is around the primary (black wire). A loose connection will build heat, as will a short. I would be worried that the protector is not protecting anything, at this point.
