Part 2: the technical dictionaryWhere do you look up what a word means?

Part 2 is nothing but definitions. Only 2 questions come from it directly — but you will be thrown back here from anywhere in the paper the moment a question says "describe", "is defined as" or "what is meant by".

A typical question: "Which describes the neutral conductor?" Part 2 gives it as a conductor connected to the neutral point of the system and contributing to the transmission of electrical energy, and the answer falls straight out of that first sentence.

Two examples:

The bits of Part 2 people forget are there

Part 2 is not only words. Towards the back of it you'll find:

• The symbols and abbreviations list — In, Ib, Ca, Cg, Zs, Ze, SPD, MET, ELV and the rest, each with what it stands for, and often a pointer to the regulation that uses it.
• The earthing and bonding figure with its key: B main earthing terminal, M exposed-conductive-part, C extraneous-conductive-part, and numbered conductors — the protective conductor from an exposed-conductive-part back to the MET is the CPC.

That answers a whole category of "which conductor connects X to Y" questions without leaving Part 2.
