pyro

[chris gray]

i'll set the scene:
were doing a rip out. theres hundreds of meters of pyro which im unable to find the ends of.
is there a means by which i can test to see wether they are live?

 

[pushrod]

carefully split the cable and use a clamp meter?

Seriously???

 

[pushrod]

should have said put on the biggest pair of marigolds that you can find first

 

[SEC-Tom]

This may sound stupid of me but would a clamp meter only give a reading if a load is being applied?

clamp meter it? What? Sure thats hardly dangerous or a pointless excercise. Clamping them will only tell you if there is a load on it. What about it being live with no load. An approved voltage tester is what you surely meant.

Come on gentlemen.....thats 2 **** poor, infact dangerous suggestions you've given him.

In short there isn't a SAFE way of doing it save for maybe one of them fuse finders.......

Next you'll be telling him to stick his tongue on the end to see if he gets a buzz

i have given a reckless reply, that could be taken as proper advice. i was being hypothetical, and i wouldnt do it myself.

Lenny, is ther any chance that post can be removed.

Its comments/posts like mine that somebody could read without understanding and get themselves hurt!

foolish of me to even try and take the p***

 

[SEC-Tom]

Is the strip out of the whole building? Can all breakers not be turned off? Or even the main isolator to the building?

 

[pushrod]

Seriously???

sorry need to apologise was being flippant but wasn't actually thinking of MICC at all

No probs.

were doing a basement and theyre only routed through there and we cant gain access to find any ends.
guess theyre staying in then

Not being racialist with this story,but the" bending the pyro" made me remember this yarn

Many many years ago,uneducated Pakistanis were working on a site
They had noticed the locals bending water pipes to stop the flow
One was asked to turn off a mixer,he duly started bending the cable and couldn't understand why it kept running

Is pyro worth anything scrap value? Obviously it's made up of a lot of copper with the outer sheath but obviously with the mineral inside being hazardous.

 

[mogga]

unless you can find the ends and theres no way of ensuring they dont conrtol anything leave well alone I was on a site a couple of years ago everything was being removed even fixings to walls,celings the main contractors spark killed everyting out the board but there was a feed to another bit of the building coming from the DNO transformer the demolition guys were given the all clear to cut cables out except the well marked mains they proceeded untill everything went dark in the other building ( magor bank head office) as the bunch of pyros made dead by spark contained the EM for the DNO Transformer An expensive lesson was learned that day ie start at one end of cable and strip out dont just stick a hacksaw through a big bunch

 

[brucegenerator]

Allright Mogga.Cannot believe what im reading on this post.

Thats beautiful that.

 

[mogga]

was it you Lenny who replaced the Dbs recently with old 3/4 pyros?? IMO Pyro makes a crackin lookin job if done correctly but an absolute arse job if not done right Personaly Im Crapolla at it and nearly as bad at conduit

 

[chris gray]

yeah it did look pretty cool. never seen anything like it to be honest.

 

[UNG]

There is something artistic in a properly done big Pyro job.

I did quite a few of these years ago but as the cost of Pyro increased and Firetuff became the preferred cable for fire alarms you just dont get to use it much these days.

 

[Sintra]

Doing a large project with all fire alarms, em lighting and plant / boiler houses in pyro. Some of the younger guys aren't looking forward to the challenge though.

 

[blackiel]

Cant blame them,did 14 months on pyro for a fire alarm system on a well known london hospital....The monotonys the killer!!
