Removing the strain relief

And the function implied from its name!;)

Oh and it 'secures' it!

Have you ever tripped over the power cord and pulled it out of the wall. If you have, you know what the strain relief does. Without the strain relief, the wire connections on the inside would have been pulled loose.

Would something like this work, though I don't know what size the hole for the cord is?

Our only choice locally is Home Depot or Lowes. Only thing that Lowes shows is strain reliefs for data cables, and the above is the only thing that shows for the local Home Depot. Any other store, I might as well order the precise part online and pay shipping because the gas spent to get to an Ace Hardware or an electrical supply place would be about the same as shipping.

Yes, but, you will have to greatly enlarge the hole to over an inch diameter. Those who have done a DIY PP upgrade can attest to the hardness of the motor pan. If you have any electrician friends, borrow a hole punch.(3/4" trade size) Make sure there is clearance for the nut inside.

IMHO this is an excellent choice.

P.S. I believe the 'gland' will accommodate varying size cords.

Well two sizes anyway![ATTACH]19026[/ATTACH]

P.P.S. There may not be enough room for the 3/4" version to clear the motor mounting bracket.

I really prefer the Heyco strain relief for this particular application.

But, whatever you decide to use, buy the strain relief and check for clearance on the inside of the motor housing BEFORE you enlarge any hole.

Skeptical about a chassis punch: I have chassis punches (by Greenlee) but I doubt that my punches will work in the metal that is used in that motor housing.

I just got back from HomeDepot. I picked up a multimeter. This time I asked the guy who was opening up the case to get the multimeter if he knew what I meant when I said I needed a strain relief. He said what type do I need and what is it for. I got a different type of strain relief than I posted, also a much lower profile. They have several different sizes of this type, so if what I have does not fit, there are other sizes to go with.

The other day at HomeDepot, the guy helping me find female blade connectors did not know what a strain relief was, and I had to show him one on the back of a washing machine.

A 'Greenlee' punch will 'get er done'. An electrician would have the 'hydraulic' version.

Note added emphasis!!!!]

Ok, it is now official. I have been reading way too much about Shopsmiths. I first read the above as "Greenie" punch.

Hope the '1/2"' one will work. Much nicer $$$ as well!

S'allright! Dusty has chassis pushes!

Yes the Greenlee chassis punches are less robust than the electrician's version.

I have used a large(> 1")chassis punch successfully on a motor pan.
