NTABID Posted October 29, 2017 Share Posted October 29, 2017 A couple of pat 123s have failed their PAT testing through lack of strain relief on the cable. Has anyone got an easy fix for this, please? Link to comment Share on other sites More sharing options...
gyro_gearloose Posted October 29, 2017 Share Posted October 29, 2017 So has your cable clamp fallen off and gone missing? I've just been browsing some Patt 123 pictures and they all seem to have a metal cable clamp to retain the cable. Link to comment Share on other sites More sharing options...
Dave m Posted October 29, 2017 Share Posted October 29, 2017 There are plenty of strain relief cable glands around that will do Link to comment Share on other sites More sharing options...
ianknight Posted October 30, 2017 Share Posted October 30, 2017 A couple of pat 123s have failed their PAT testing through lack of strain relief on the cable. Has anyone got an easy fix for this, please? "lack of strain relief"? Not sure how this is a PAT fail - the visual inspection of the test should ensure that the cable is secure on the fitting and not damaged but a strain relief or lack thereof (in my opinion having tested 100's of Pat 123's) isn't part of the test. http://www.serviceguy.co.uk/wp-content/uploads/2017/10/strain-relief.jpg [This is what a strain relief is to me] It would only become a concern if next year, the cable was damaged at the entry point to the lantern but mostly that can be alleviated by using some PVC tape around the cable so that the metal cable clamp doesn't bite in to the cable. If the cable clamp is missing then it can be tricky to fit a replacement clamp on Patt 123's but I have done it and seen it done by fitting a nylon gland on the side of the bulge at the base of the lamp assembly - it's fiddly and takes some work but is do-able.

sunray Posted October 31, 2017 Share Posted October 31, 2017 Nylon stuffing gland on a 123? Two issues as far as I see this: 1) nylon stuffing glands are not classed as strain relief on their own and 2) Nylon stuffing glands are not rated at the temperature of such a lamp fitting.

Ok then - Nylon, polyamide or metal - I was using it as a generic term but the point is - no strain relief on a Patt 123 isn't a PAT test fail in my opinion :) Link to comment Share on other sites More sharing options...
alistermorton Posted October 31, 2017 Share Posted October 31, 2017 It's something I've often wondered about - if you look at the back of a minim, there is a version (with the non integral moulded handle, where there is a "bakelite" handle screwed to the case) and where the cable enters via a standard cable relief grommet like one of these:http://img.directindustry.com/images_di/photo-g/70125-3997593.jpg So I wonder how come that's ok on a minim (that's how they were supplied) but a similar one on a Pat123 wouldn't be acceptable.

paulears Posted October 31, 2017 Share Posted October 31, 2017 Strain relief isn't a PAT fail is it? The original design doesn't involve any modern kind of additional layering, just a clamp onto the cable sheath? The clamping saddle on a 13A plug doesn't provide cable sheathing - surely a fail to the 123, would be the same as a 13A connector? Clearly if the internal conductors can be seen that's wrong, but that's not what we're talking about here, is it? Link to comment Share on other sites More sharing options...

It's not really clear, I assumed the OP must mean the 'saddle clamp' is missing - perhaps he could enlighten us? Link to comment Share on other sites More sharing options...

PAT tester has said that because of this it's a fail. Do I gather from your kind replies that the only acceptable solution would be a suitable high temperature gland? Does that therefore mean metal?

Hilary Watts Posted November 3, 2017 Share Posted November 3, 2017 Do they not make metal saddle clamps any more? I have several that might be about the right size that I have removed from old pieces of equipment and you are welcome to have one if it's any use. What is the diameter of the hole?

paulears Posted November 3, 2017 Share Posted November 3, 2017 Surely we are talking about a bit of aluminium, and the application of a file and a drill! As you will need the file and drill to wreck and install a proper gland, why not just repair the old one properly? Once you fit the new saddle, your old light is fixed?
