electrical connection lubricant

i noticed the hot leg plug on a 30 amp hookup gets charred or burned due to heavy draw and poor connections..is there a product that will enhance the connection and lessen the chance of a burnout..thanks..jim

Jim, I'd replace it with a new plug. The prongs in the molded ones tend to get loose, probably from heat, from electrical resistance.

I replaced mine on my old coach. 15 minute job. Can purchase new ones at CW.

One thing you might do is take a piece of emery cloth and keep the prongs shiny. I would not recommend any grease, as it's an insulator (as is WD-40). Will generate more resistance, and thus more heat.

thanks..i've replaced several over the years and do clean the prongs as you say but somewhere i read about some salve or gel that would enhance contact and reduce heat..can't remember where though..jim

White Lithium works well on 12 volt but have not used anything on 110.

Ford, for one has a product like this. The part number is F8AZ 19G208 AA. I don't know if it is still available or how much it is. I have had a tube of it since before I retired. A tube will last a lifetime even if you share with friends.

What you are looking for is Dielectric Silicone Compound. Got mine at the local hardware store. Made by AGS. Even refers to it's use by GM and Ford. Works fine, lasts a long time.

hi..do those products specify they can be used on 110v 30amp lines..thanks..jim

The first that I can remember running into the dielectric compounds in the trades was under the electronic ignition module n GM cars. I was used to carry away heat and provide a good electrical and mechanical connection between the module and distributor breaker plate. The voltage here runs up to 500 volts. The next place was the ignition spark plug wires and rotor gap on Fords. Voltages up to 50,000 volts here. I use the dielectric grease on both by 30 amp pig tail and my 50 amp connections.

I use the dielectric grease on my shore power plugs and haven't had any problem with them turning color as before. I also use it on the remote satellite dish connections and no more problems with corroded center electrode. Used it on exterior light bulb bayonet bases and ended corrosion of those. I obviously think it is a pretty good product.

homer..thanks..could you tell me where you buy it and a brand or label identification..jim

JIM: Happy to answer your question. What I have is called "GB OX-Guard". Made by GB Electrical Inc. of Mil Wis. Claims: "guards against oxidation and improves conductivity and produces a cooler operation". I have found this to be very true.
I purchased mine from a local electrical supply house. However, I am certain any big box home improvement store has it, i.e; Lowe's, Home Improvement. It comes in plastic tubes from 1 oz up to larger sizes. A little goes a long way. I keep a tube in the work shop and another in the motor home. I use it in the motor home more than anywhere.

Don't know if Copper to Copper connections are included as benefited, but the idea seems to make some sense.

It sure has worked well on the blades of my power line connector to the female socket in the power pole. They used to discolor and I would have to use light emery or wool on them to clean them. Not necessary any more, so copper to copper or brass is benefited.
