Any recommendations for good books on the practical aspects of domestic
wiring. the onsite guide is pretty good for all the mathematical and
regulatory stuff but am looking for something that covers the practical
installation.

My favourite is Home Electrics edited by Julian Worthington, but do be
aware that it was published (Orbis) in 1981 so any rules and regs will
be out of date, although the actual practicalities will be unchanged.
Lots of coloured pictures and diagrams.

eBay item 382998445963, 2.56 BIN, including postage.

The above book was part of a series including plumbing, metalwork,
general DIY projects, woodwork and probably others. Dummies Guides from
nearly 40 years ago, but lots of great info and illustrations.
