FP Cable Is Not Always Suitable

[Engineer54]

but as said all down to good practice, and am a little surprised that E54 doesn't support that.

I would support any good practice that held creedence, unfortunately refraining from blowing out a MICC pot prior to sealing doesn't hold any credence for me. As i say it doesn't make one jot of difference...

You may well be correct, but I would still say it is good practice as its always possible a little spit may follow.

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

thanks for the offer of a spare potting tool guys, the local wholesaler's are very good and he has managed to get me one at a reasonable price.

£35 inc vat etc.

not bad considering I only spoke to him about it tuesday after 5pm

no you're better with a battery one,mind you I 've got a wind up one somewhere if that's what you want.lol

 

[shanky887614]

got my potting tool today so gave it another go

 

[Guest111]

have you meggered it yet?

Take it to work and IR it mate, just out of interest.

But in the meantime, plug it in at home and see if your RCD hangs on.

I did take the other one to work and did ir it, got about 60Mohm.

to be honest I didnt cut any off coil or try to get any moisture out of it first before I made end of so who knows.

this one should have a lot higher reading?

it was a little odd because it fluctuated from 50mohm to > 299 at 500v. im guessing batteries in tester could be low because didnt get constant reading

or there may be a slight bit of moisture there and the IR test is drying it out, thus readings will rise as you keep the tester on it.

The correct method of IR testing a new circuit/build is by applying the test voltage for a minimum of 1 minute... Most electricians, will if you're lucky IR test for 10 to 20 seconds. lol!!

thanks for that, I have never heard anyone mention that and nothing at college etc.

Tut. tut!! They don't seem to be teaching much at all at college these days....

they only teach the questions/answers that are in the exam now, only reason I didnt need any resists in final year was I studied off my own back online.

everyone else needed a resist or really struggled.

one question in jtl test was how deep is recommended for a bore hole for the average sized house.

no mention in revision books etc that we were supplied with etc and even tutors were clueless when I mentioned it after exam

 

[Engineer54]

Bore hole, ..bore hole for what??

 

[shanky887614]

Bore hole, ..bore hole for what??

ground source heat pump.

renewable crap in the new nvq

 

[telectrix]

thought a bore hole was where you put the father-in-law when you couldn't take any more of his verbal diorrhea.
