Thoughts on twisting CPCs together.

[Lumie]

Just wondering on peoples thoughts on twisting CPC's together. Worked with multiple sparks over the years some do it some don't. The ones who do it argue that there is less chance of losing continuity, as even if they do become loose in the back of accessories they are still twisted together. However I don't as I think it is bad practise for when it comes to the testing side and also lengthens it.

Whats your thoughts?

My thoughts are I should definitely have better things to be doing on a Wednesday night than thinking this over!

As I tend to loop over the conductor when terminating at the switch or earth terminal this precludes twisting together. And yes it is a pain when having to untwist and possibly damage earths for testing. Although I was taught to do that when the devil was a boy. But don't tell anyone on this forum though.

 

[danzor]

Don't do it, think of the poor bast.... who has to test it

 

[SparkyChick]

I'm with you guys, I don't like it. Makes it a nightmare for testing and increases the possibility of breaks due to stress and work hardening of the copper.

Nightmare for testing, but it can give a good connection. My thoughts have been mixed over time, but the final decision was regarding twisting at sockets, if they pop out the terminal they will still give you an end to end, although the socket won't have an earth, I prefer to have each leg into separate terminals, less chance of losing the earth.

Lectric don't go around bends like it does straights.

Twisted cpc's in fuseboards are a complete pain in the rear......

 

[Hellmooth]

In a fuseboard they are the worst thing, twisted and in the same sleeving.......

Never mind cpcs lightly twisted , feller i used to work for use to make me twist lives (line i know dear) and neutral together ,he would check to make sure they where evenly twisted and that one core wasn't twisting more than the other.

Seen this loads of times, utter madness springs to mind! Trying to find a fault on a ring socket, un-twisting the conductors to test leg to leg, which causes them to become weak and snap........they were short enough to start with.......

More of a Jive man myself could never master the twist.

he also though automatic wire stripper's where for diyer and 4mm earth sleeving was sound for lighting circuit . He is minted and his two daughters are fit so maybe he was right

They do a lot of sport them two girls.

Firm I worked for during first 18 months of apprenticeship twisted all 3 conductors, the college tutor was shocked at them teaching me that, as it was a well respected small family firm, and said if that's what they want done then do it, but not in college or during AM1&2.
Never done it since I left them.

automatic wire strippers ARE for DIYers!

 

[Phil Thompson]

I thought they were for Year 8's technology classes lol

no way i love my ck stripper's .Never used a set for years and when i did i felt a bond only man and tool can know

Used to be common practice in the 1960s to twist conductors together, no cpc sleeving either. I try not to think of it now, gives me nightmares.

Twisting line and neutral conductors is also for DIYers.....And also cutting them ridiculously short is a sure sign of DIY

But they saved 0.75p on not having that extra 25mm!

I always did it at switch positions, if multiple cables. sleeved singular though.

 

[telectrix]

if i have 3 or more cables, i usually terminate cpc's in a wago, then a fly lead to the box.

 

[Wilko]

I was brought up doing the twist, but I've moved on now ...

Here's one good reason to get out of the habit of twisting those conductors

Where its necessary to have high integrity earthing using Ring finals

Regulation 543.7.1.4 requires that where two protective conductors are utilised they are to be terminated independently of each other at all connection points, including accessories

Find too many done by electricians in the 50's or 60's seem to be very short. Maybe price of wire was more of something.
