FP Cable Is Not Always Suitable

[davesparks]

Looks good from here, cable sheath just half a gnats whisker inside the pot and the earth tail in the right position relative to the cores.

Grab the end of the cores with a pair of pliers and give them a good hard tug to straighten then out, it'll make sliding the seal on a tad easier.

Agree with dave, a good tug with pliers on the 2 cores and it is looking good

Not bad for a first attempt, I've seen a lot worse. Did you IR it?

You probably saw one of my first attempts Trev!! Got a right ear-bashing for it... no shroud, pot not straight and screwed on to far...

btw - I've a spare one of these if MDJ can't set you up...

Edit - didn't realize the pic was that big, i'ts only for 20mm pots

As an apprentice I was given scrap ends to make off, After a while and some intense inspections of my efforts I was allowed to use potting compound. The first end I made off that actually went into service made me a very proud puppy spark.
Afaik it's still there to this day.

your gran kids might get the chance to rip it out while complaining its better than what they are replacing it with you never know

Well so far we're one from three and it looks like it's staying that way. Grandson will not be a spark if I've got anything to do with it.

No point in testing until you have potted the gland......this will be another learning curve, testing the insulation with one reading..then testing 24 hours later, with another reading. Full marks, for taking the time to practice and post your results. In the next few years, when industrial projects need installing and renewing...The quick course guys will be left to their house bashing, whilst others will be back in the thick of it.

A decent effort.
when doing it for real remember and put the compound in from one side only of the pot.
keep the compound clean and free from bits of swarf etc.
i wouldn't blow in the pot as mdj suggests I would give it a tap and make sure it's clean myself
like all black arts practice is the key

Blowing in the pot is potentially bad news. You could have bits of swarf in there which could blow up into your eyes.
Tappy tappy is much better.

to be honest I didnt blow into it, I wiped conductors first to get rid of most of it then tap.

I didnt touch compound either, I used the wrapper and overfilled it from one side to stop the formation of any air pockets

 

[davesparks]

Beware of a tiny thread of brass/copper swarf which can sometimes appear in the pot as you screw it onto the cable.

Also pop the megger on it before you put the compound in, and then just before you crimp it, and then after you crimp it. this was you have a chance to correct things before you crimp it and get to the point of no return.

The reason I was taught not to blow in a pot is because the moisture from your breath can dampen the mineral - of which would be sealed in with the compound.

Shanky...are you using a cutting compound or oil when cutting....if you find this messy, old trick from an old sod...is use a candle, just as good, less mess and saves you joist blade

While it's a possibility the likelyhood of it happening is fairly low
