Energy Saving solutions – use Time Lag Switches for reducing the energy consumption

There is a quick and effective way to reduce the energy consumption for the lighting applications – use time lag switches(time delay switches)! The way these wiring accessories work is – by pressing the button/the pad, the lights turns on and, after a set interval of time, the light turns off! The range of time lag switches found at sparksdirect.co.uk do not require a neutral connection – they can simply replace the existing light switch; also, in most cases they represent a simpler/cheaper/more effective solution for lighting control.

Where can you use a time lag switch? The Time Delay Switches are ideal for the lighting applications on the stairwells(staircases), in the meeting rooms, on the corridors, in the entrance lobbies, the store cupboards, at the toilets, etc. They are fully suitable for new or retro-fit applications.

General Key Features and Benefits of the Time Lag Switches

• The time lag switches do not require a neutral connection(easy replacement of the existing light switches).
• The time lag switches are multi-way – all models can be act as 1 way, 2 way or intermediate switches.
• High rating – they switch flourescent and incandescent loads(see their particular specs).
• Tamperproof switches: the lights turn off even if the button is wedged down.
• Optional: weatherproof – for placing outdoors, outdoor lighting control.
• The Time interval – up to 20minutes, ensuring user safety(can be manually adjusted).
• Unless otherwise specified, these time delay switches take 10A of lighting including incandescent, fluorescent, compact fluorescent, low voltage (switch primary of transformer).

Short guide to the 17th edition of the Wiring Regulations

Taken from the official small guide to the 17th edition of the Wiring Regulations, this guide presents the names of the main chapters of the latest version of the Wiring Regulations, together with a list of modifications that were made to the previous versions of these regulations.

The IET (The Institution of Engineering and Technology) put out some time ago the red-cover book containing the Wiring Regulations 17th Edition, BS 7671 (The IEE Wiring Regulations), which are the national standard to which all domestic and industrial wiring must conform (you can buy it online here). The 17th edition contains substantial changes to align with European documents. The IEE Wiring Regulations are produced by the Institution of Engineering and Technology (The IET). The IEE is an imprint of the Institution of Engineering and Technology and is used for all books related to the Wiring Regulations. Continue to read about the Table of contents and a little introduction to the 17th Edition Wiring Regulations.

The BS 7671:2008 Requirements for Electrical Installations was issued on 1st January 2008 and came into effect on 1st July 2008. The installations that are designed after 30th June 2008 are to comply with BS 7671:2008. These Regulations apply to the design, erection and verification of electrical installations, also additions and alterations to existing installations. Existing installations that have been installed in accordance with earlier editions of the Regulations may not comply with this edition in every respect. This does not necessarily mean that they are unsafe for continued use or require upgrading. Continue reading about the changes to the 17th Wiring Regulations.
