NEMA 14-50 male plug recommendations

A client wants to use their 8kW generator to power a critical loads panel if the power goes down. That part's easy. He's not happy, however with the "plugability" of the male NEMA 14-50 plug that connects to the generator. The last guy built him a cable with a "standard" range-type plug and it's hard to grasp to unplug. He's older, and has arthritis.

Thoughts on a plug like this:

I'm slightly wary of buying electrical parts from Aamzon, but this appears to carry an ETL listing.

Also looking for recommendations for a plug with better strain relief (it such a critter exists).



Thanks,

I don't think the amazon one is listed. A lot of products have been putting the Intertek ETL listed sticker and a random number. I couldn't find anything on their site for the product.

I like it. Now... how to buy one. Their website is useless for locating someone who will sell one.

EDIT:
Never mind - I found a dealer:

What 8KW generator has a 14-50 receptacle? All of the generators I've ever seen under 10K have an L14-30.

Why not just buy a ready made cable of appropriate length and chop the female end off? I've never been impressed with the qualify of any replacement 14-50 plugs.

if you look at how the molded premade cables are made, a quality assembly plug is way better.
 
I would go with a twist-lock connector, the blades are easier to remove after unlocking, because they lock, so they don't have to rely on the blade pressure to do that too.

That RV plug is nice though, it's available from RVEParts.com, for less than on Amazonk...

Firman HO7533. It's a dual-fuel (gas or propane). It claims 9400W start/surge, and 7500W run on gas. Slightly lower on propane.

I took a photo this afternoon to make sure, and it is indeed a 14-50 receptacle. Clearly not using it to full ampacity (9400W = 39A) but still more than 30A.

It also has a L15-30 twistlock, L5-30 twistlock, as well as a GFCI duplex receptacle. Electric start too. Nice little unit.

L14-30 not L15 right?
 
I would be tempted to use a the L14-30 with a 10 AWG cord. It would be loads better for the old guy to operate, and the cord will not catch fire should he ever demand that last 1.5 amps. Besides that the generator surely has 30 amp breakers for that socket.

i wouldnt. the 30a breakers are likely little push to reset thermal breakers with terrible trip curves, i wouldnt rely on them to be able to continuously draw 30 amps.
 
The original Amazon item is listed with intertek. I sent in a compliance request form and they said it was authorized. Sorry for the confusion.
