I'm none of those things.Good to see your just an ignorant abusive bum as always.
FFS - you went ahead and wired it up using a cpc as a live conductor?Thanks for the feedback, unit is working successfully
Which is quite correct, and I'm not going to argue that point.Green & yellow should NEVER be used for anything other than earth.
The OP describes a green/yellow cable core of a multicore cable, not bare cpc, which he'd like to use as a live conductor.That's nothing but a dangerous bodge.
There's nothing in the OPs post to say that it is a green/yellow insulated core. It's more likely to be a CPC in a T&E that's been sleeved green/yellow - and depending on the size of the T&E, remember that the CPC may not be the same size as the other conductors.A sleeved green and yellow is just as safe as any other colour and you know it.
I'd suggest that latter statement says more about your installation than the abilities of a sparky.Did you know 9/10 Sparks couldn't wire a boiler and get it to work as designed and I would go as far as to say 99/100 sparks couldn't wire one of my installations without a line drawing.
No I didn't know that, but then that is because it is a false statement. A typical boiler control circuit (internal) or heating control circuit (external) is going to be no more complicated then a typical motor control circuit or building management circuits. Both of which are far less likely to be worked on by DIYers with limited understanding of their purpose.doitall said:Did you know 9/10 Sparks couldn't wire a boiler and get it to work as designed and I would go as far as to say 99/100 sparks couldn't wire one of my installations without a line drawing.
Earth conductors must be reasonably assumed to be connected to earth and not used for any other purpose. When you cut into an existing cable or replace an accessory/appliance you will always test to ensure you know what each conductor carries. (DIYers may not.) However that does not change the fact that the designated earth conductor is just that - designated for earth. You may be sleeving a blue wire to show it is a switched live but it would always have been capable of carrying current. A designated earth should never carry current except in a fault condition in order to protect life and property. Doing so is a direct violation of BS7671 514.4.2 which states that cables coloured green/yellow throughout their length should not be used for any purpose other than as a protective conductor and may not be over marked at their terminations other than to aid circuit identification as permitted by Regulation 514.5.2.doitall said:Nothing wrong with over sleeving or putting black/red tape on a multicore of any colour.
In which case there are 1000s of posts by, and pictures of work done by, dangerous ignorant people like you.There are 1000s of posts and pics showing just that, where the OP is swapping like for like.
Yes there is, but you are so thick that you don't understand that.Nothing wrong with over sleeving or putting black/red tape on a multicore of any colour.
Apart from for twin & earth, where the separation of cpc is obvious and defined, IIRC there is no standard for multicore cable which stipulates or allows different cores of the same cable to have differing insulation characteristics based purely on the colour applied to the core sleeve.You may be sleeving a blue wire to show it is a switched live but it would always have been capable of carrying current. A designated earth should never carry current except in a fault condition in order to protect life and property.
It states single core cables quite clearly. This is for the benefit of problems which may arise from incorrectly identifying singles in conduit and trunking.Doing so is a direct violation of BS7671 514.4.2 which states that cables coloured green/yellow throughout their length should not be used for any purpose other than as a protective conductor
It states they may not be numbered other than for circuit identification, nothing mentioned about over sleeving.and may not be over marked at their terminations other than to aid circuit identification as permitted by Regulation 514.5.2.
A multicore cable, when the outer core is removed to expose the cores, becomes a collection of single core cables as far as identification is concerned. It makes no difference how they are grouped, whether it be singles through conduit or a multi-core flex/T/3C+E/etc - when the cores are exposed then identification at the terminations will not be able to override the cable colour/pattern. Green and Yellow cable is designed for one purpose only, for use as a protective conductor. Regardless of any rules or regulations you should never deviate from safety standards.It states single core cables quite clearly. This is for the benefit of problems which may arise from incorrectly identifying singles in conduit and trunking.
