Does anybody here know of a standard 6 wire twist lock. My application is an outlet box on the end of a cord reel on a fire truck.

The cord is a 10/6 SOW and in the outlet box there is a 30 amp 240 volt twistlock, a 15 and 120 volt twistlock, and two regular 5-15's. There are 3 circuits going to the box, two hots an a common ground for the 240 twistlock, hot, neutral, and common ground to the 15 amp twistlock, and one last hot for the 2 5-15's (they will use the neutral from the other 15 amp circuit as a multi-wire)

We want to have a twist lock so we can disconnect the outlet box when bringing in the cord reel.

The best I would find was an L22-30 but that was only five wires.

Any ideas?

Thanks, Jim

I was looking into the AMP mil-spec round connectors, just trying to figure out which one to get to have 6 #10, the closest I could find was a 7 pin for #8.

Thank you for the link to Meltric, I looked online and requested a catalog, they seem to have a good product, just need to figure out how to write them into the spec.

Meltric has great tech support I’m sure if you give them a call they can help. Lots of choices on how to assemble the devices I find it best to call for peace of mind.

mil-spec round would be perfect for this application, as they're designed specifically for rugged used like this. Military has gone pretty much completely crimp now.

Note that when ordering military connectors, the backshells and pins are ordered separately. I don't believe there are any #10 pins, and #8 are only in a limited # of styles. I believe #8 crimp pins will #10 cable, though I'd have to pull the specs to verify.

Gonna cost you $$$ for mil-spec, though. Uncle's got deep pockets.

Another option would to be having two plugs-one for the 240V 30 amp and the other for the 120V, Raychem (amongst others) make "Y" heatshrink boots for splitting cables. This method will be easier as it will allow the use of standard plugs for the services rather than specialised connectors. Problem is the strain on the "Y" junction due to strain may cause more grief than good.

I had a look in Australia for you, I found an IP66 rated connector which had 7 pins but only good for 20 amps.

This has become a lost art but if you do go with the "Y" configuration, "lacing" the cable (tied up with wax impregnated lacing cord) before you shrink wrap it will make it last forever. We had cables like this in the olden days that were just laced and wrapped with cloth tape and they did well for decades.
