Progressive Industries EMS HW50C

[Gardner Yeaw]

Dick,
You are correct about cold flow. I used to work with three phase
mainframe water cooled computers, and whenever the electricians
wired up an new plug, they would wait 15 or 20 minutes and go back
and tighten it again. One year there was water running into the
computer room under the raised floor. We went around and lifted the
connectors up and put them on wood blocks. I grabbed the cable from
one of the machines and all 4 wires pulled right out of the
connector. (208 three phase power). Lucky I was at the machine end.

So now once a year, or if I am doing anything electrical in my
house, I tighten the ground and hot connections on my breaker panel.
I just run down where the common and ground wires are connected then
do each breaker connection. They always tighten just a little. (I
don't use excessive force, just s firm twist).I had an electrician
do the mains comming in cause you can't shut them off and I don't
have the proper tools or rubber gloves.

have for years, first on boats and now on the coach, check the plug
yearly. Completely dissemble the plug and check for damage ,i.e.
over heating evidence, and tighten the screws. I have noticed even
without over heating damage the screws will loosen over time. I
believe it is called "cold flow". The copper wires actually move a
little due to the pressure of the screw clamp. I've also noticed
this in the main breaker panel, though not as dramatic as the plug.
Probably due to the stranded conductors as opposed to the solid
conductors in the main panel.

check it out. Especially these 30 amp cords that have a 50 amp plug
at the coach. The park connection should protect with a 30 amp
breaker but I have noticed that you can't depend on that for what
ever reason. I once witnessed a power pedestal on fire across from
my boat. It had just caught fire. The reason was, you guessed it,
the boathouse's plug was defective - very loose screws.
