Video – short Domestic Consumer Unit guide to the 17th regulations

We have previously posted the Hager guide to the 17th editionThe Consumer Unit Guide to the 17th edition wiring regulations and the Consumer Unit Arrangements – and now here’s a short video explaining the main things one needs to care for when wiring the different accessories in the home environment. There are mainly three categories of persons who can do this: A skilled person(a certified electrician), an instructed person(who can also work with the equipment), and the ordinary person(someone who lives in the household). It is recommended that most of the electrical installations in the house be done by certified electricians, who know the latest rules and regulations, especially the 17th edition wiring regulations.

  1. My consumer unit dose not have the facility to locate a circiut breaker for a fire alarm without connection to the RCD. Would fitting a battery back up alarm get round this? My consumer is a 2 way split with RCD on both sides, with the bus bar feeding from both RCD’s

  2. It’s not easy to give you an advice regarding this – you will need to check the 17th edition regulations about this particular situation.
