Smoke & Carbon Monoxide Alarms
If you require our services in your home and have not yet fitted smoke & carbon monoxide alarms, we would be pleased to do this for you.
We can provide any approved battery or hard-wired detector, including those incorporating emergency lighting and specialist items for the hard of hearing.
Movement Detectors (PIR) connected to high-powered Halogen Lamps are an excellent deterrent to intruders and are a very cost effective and simple way to improve your safety and security.
Power Breakers (Residual Current Device)
Power breakers are most commonly used to provide additional safety when using portable electrical devices outdoors.
The device prevents the risk of any harmful electrical shock to the operator.
The devices are available in a variety of finishes for installation in conservatories, garages and on outside walls
New Fuse Boards
Now that the UK electrical industry has finally seen the latest changes to the 17th Edition of the IEE Wiring Regulations (BS 7671), the new mandatory use of Residual Current Devices (RCDs) are now in effect.
Whilst residual current devices (RCD) have been in use for many years, the new 17th Edition requires electricians to consider the use of RCDs in many more applications than the current standard requires in order to improve building protection.
The basic function of an RCD is to trip and disconnect the supply of electricity in the event of an earth fault in order to prevent electric shock and fire risk. It does this by detecting the imbalance of currents between the live and neutral lines caused by a fault to earth. Drawing attention to the importance of using RCDs in the right context and with the right equipment, the IEE Wiring Regulations provides guidance on how RCDs should be incorporated in new builds & wiring upgrades to your premises.
One example is the requirement for cables concealed in a wall/partition at a depth of less than 50mm in domestic installations. Such cables will need to be protected by an RCD rated at 30mA or below, even if they are in a safe zone. This comes into full implementation on July 1st 2008, after which all new installations, alterations and additions designed on or after 2nd July 2008 will need to comply with the new requirements.
The only exception to this will be if the cables are enclosed in an earthed metallic covering / conduit or equivalent protection capable of resisting nails, screws etc. This is also the case for cables installed in metal-framed walls - a very popular construction technique at the moment.
30mA RCD protection for ALL sockets:
Additionally, all socket outlets rated at 20A or below within a domestic building will require 30mA RCD protection. This means that all ring main circuits from consumer units will either need to be fed from the RCD side of a traditional split load board or have individual residual current breakers with overload (RCBO) ways.
Because the RCD is sensitive to current imbalances, it is not practical to fit just one device to protect an entire house. If a fault develops within one circuit, all circuits would be switched off immediately. By using individual and grouped RCD protected ways in combination with one another, the required protection can be provided whilst maintaining continuity of supply to other non-affected zones within the installation
