Finder publishes handbook for domestic and commercial electrical installations

The guide begins with an introduction to relay-controlled lighting systems, which includes a summary of the appropriate international standards and approvals and a discussion of the benefits of a relay system in comparison with a traditional wiring system. The main part of the book then presents basic electrical parameters and detailed wiring diagrams for Finder’s lighting control relays – light dependent relays, staircase timers, step relays and dimmers, time switches and PIR movement detectors. Additionally, sequencing tables are provided for the step relays. Also included in the book are relay interface modules, level control relays and modular timers that, although designed for general and industrial use, can also find applications in a building environment.

The Electricians’ Guide measures 16cm x 11.5cm, making it easy for the electrician to carry in his or her pocket for quick reference when required.
