FP Cable Is Not Always Suitable

[shanky887614]

Had to make off a few practice ends and make off two for the unit 305 practical exam.

that was your colleges choice, I didnt touch it at all in mine. was shown a pic of it and shown some compound and that was about it.

ill be making some ends of myself quite soon and later on might have to at work so it will be good practice

For the 305 practical, We were given a diagram to wire up using different sorts of cables, so for example from the board to a 1 way light switch in twin, and then from the board to fused spur in pyro, board to socket in SY flex etc. The cables were set buy City and Guilds. Dont have the sheet anymore or i'd post a photo. Had to do it for the exam.

how long ago was this?

when I did my level 3 in college there was 0 install. only thing we did was testing.

used twin and a little bit of singles. swa twice that was in level 2

2330 I meant.

sorry didnt read tye pyro bit.

colleges dont usually even have any onsite now.

spoke to cef today about some crimping pliers and they were telling me the last pair he sold was over 10 years ago.

We have a pyro "bucket" at work (all the odds and sods from the bottom of peoples tool boxes), its been used once in 2 years where we had to joint into an existing Pyro install and extend in FP200. I had to get one of the time served guys to do it, he hadn't done one for 15 years...... still used in chemical plants and other high risk industries....

Same at my college. We had to use Pyro, swa, FP200, SY, Twin, Cat5, singles, and various different flex.

I think it is important to be shown how to terminate pyro. Every apprentice should be taught imo.

Cat5 really? Krones or plugs?

Why would you extend pyro with fp200? Seems a bit daft to me.

I was taught that you should always extend cables/wiring systems with the same or better cable, not to extend them with a lesser system.
For example you extend steel conduit with steel conduit or you extend MI with MI.

Just made off in to a data point witha punch tool.

I was taught the same way mate as many others will as its good practice. I had a conversation with a guy from Cormeton once who was commissioning a fire alarm system that had been extended from pyro to fp and he said ut can cause problems. Cant remember the reason he gave I think it was on an adressable system so may have been something to do with the systems knows which way accessories or set at or something along those lines. (Im not mega clued up on the technical side of fire alarms)

The last lad I trained asked about pyro at college and was told they didn't do it any more as it was a bit of a black art eventually I can see it being a specialised thing if something isn't done to improve training at college,lets be honest it's still widely used in certain areas so should still be taught as part of normal trade training.

That sounds like a bit of old bull to get around him being unable or too lazy to do it properly.
It's easy enough to get the polarity right on a bit of pyro, and I'm sure a earthed solid copper sheath is better than a bit of tin foil wrapped around the cores as far as screening goes.

 

[DRG]

You're probably right mate

 

[shanky887614]

first attempt at 2l1.5 using double pliers method

lovely stuff to work with, I don't know why some people really don't like it

How did you get the seal crimped into the pot without stripping a bit more sheath back to get the crimped round it?
It may be an optical illusion but it doesn't look like you've stripped enough sheath back to me

yup your right, I havent actually threaded it as far as I should have.

its caught a little bit of thread but I didnt realise how far it was supposed to go till I just did more research on youtube.

What dave means is you need to strip back more orange sheath so you can slide the gland back, you need to crimp the cap into the pot firmly, you can't do that with the gland in the way fella.

true, to be honest Its a bodge at home till I get hold of a crimper.

I crimped it into the pot by putting one side of the grips on the very bottom on the gland and the other side on the top of the pot.

I would like to have used a proper crimper but I don't have access to one at the moment

aye I know pal, bear with me.

 

[davesparks]

Yeah sorry, I meant the orange over sheath not the copper sheath, I should have made myself clear.
