I was unaware that what the Wiring Regulations actually say could be changed by voting.
To all readers:
For a circuit as described above, 543.7.2.201 requires compliance with 543.7.1. It does. It says so in clear and unambiguous language. Only people who think that they can pretend that 543.7.2.201 contains words other than the ones printed in the Wiring Regulations would say otherwise.
So 543.7.2.201 leads us to 543.7.1.
543.7.1 (in 543.7.1.201) requires that a circuit described as above have two individual protective conductors. It does. It says so in clear and unambiguous language.
Further it says that each of those two individual ones must comply with Section 543. Each of them. As individual protective conductors, not as a pair working together. Each of them. It does. It says so in clear and unambiguous language. Only people who think that they can pretend that 543.7.1.201 contains words other than the ones printed in the Wiring Regulations would say otherwise.
So 543.7.2.201 leads us to 543.7.1 which leads us to Section 543.
Section 543 (in 543.2.9) says that a circuit as described above requires a protective conductor to be in the form of a ring with both ends connected to earth at the origin of the circuit. It does. It says so in clear and unambiguous language. Only people who think that they can pretend that 543.2.9 contains words other than the ones printed in the Wiring Regulations would say otherwise.
But remember that 543.7.1.201 requires two individual protective conductors, EACH ONE OF WHICH complies with 543.2.9 and therefore EACH ONE OF WHICH has to be in the form of a ring with both ends connected to earth at the origin of the circuit.
Each of them. As individual protective conductors, not as a pair working together. Each of them.
They each have to be an individual ring in their own individual right.
I'm really not sure what John is hoping to prove here. If it is that many people share with him the belief that the Wiring Regulations either say something other than the words printed in every copy sold, or contain words describing requirements which the people who wrote them did not intend to be requirements, we already know that.
But it really doesn't matter how many people vote Yes, or what % of the votes are in the Yes camp - none of that is capable of changing what the Regulations actually say.
People who vote Yes are wrong - it is that simple, that straightforward, and trivially easy to be seen by anybody prepared to read and take notice of what the Regulations actually say.
It doesn't matter how much, or how many, people argue that they believe that their alternative complies with the spirit of what the Regulations intend by the various regulations in Section 543, or how their alternative is just as "electrically sound" as what is prescribed by the various regulations in Section 543. Because Section 543 contains the immutable words which it does, Section 543 says that the arrangement proposed above does not comply.
It does. It says so in clear and unambiguous language. Only people who think that they can pretend that 543 contains words other than the ones printed in the Wiring Regulations would say otherwise.
