So, hoping the statement in subject line is clear, but if it isn't. I noticed today that the 50amp plug on my main service cable is loose when I turn it into the receptacle on the RV. Can this be tightened by bending the electrical tabs on the receptacle in the RV, and if so what way should I slightly bend them, in or out?

Sometimes a picture really doesn't help, but I'll get one and send it next. Best explanation I have is pull or plug your main cable into your RV and note how tight it is, mine is extremely loose when I plug it in, not normal. All parts look good just too loose.

The weight of the straight twist lock connectors is a big factor. Yes, you can try to bend pins. Doubt whether it will last. Most twist lock connectors are made of better material. They do not normally show burnt marks on pins. The end that becomes loose is on the cable. Replacing it with a 90 degree, hard to find connector can reduce strain on pins.

Time to replace the receptacle.

thanks guys. I'm convinced it is the twist lock connector. As stated by Bud, it is big and heavy. There is no way into this molded piece. The receptacle on the RV is in good shape. A right angle 50a connector would probably cost as much as a new cable LOL.

Plug to Camper problem, it's loose in its receptacle on RV

Some rigs do not have Marinco style connectors. They are used more in marine applications. Plus they cost more!

Cut a notch in an upright 2x4

Endless variations like notches every 6"

2x6 option

It supports cord weight. Even a hundred pounds.

Been using this in México for 40 years

On 30/50 amp Marinco type connectors that I've seen there is always a locking ring. Two types.

now on 20 amp Twist lock. no ring but I've not seen one of those in a long time.

I have the 90 degree end on mine, non locking just plug in, it is extremely tight and is 24 years old. I have to wiggle it to remove it.

after you turn the plug to the right you MUST tighten the locking ring! you can bend the ped end but not the RV end.

I'm not sure what you mean by "Loose" but I do not think you have a problem
Are you getting good power inside? If so likely no problem

I would not bend tabs to tighten

Tighten the lock ring

have a good electric shop in your area,, cut it and have a new 90deg put on. might come close to the price of a new cord,or they might do it free. mine would do it free small town .
