Q: What is an RCD?
A: RCD stands for Residual Current Device. These are what use to be called ELCB�s (Earth Leakage Circuit Breakers). They are usually fitted as standard to most domestic consumer units in houses built after about 1980. Note that they tend to only protect certain parts of the distribution panel wiring (e.g. the kitchen or utility ring main), in a so-called �split-load� consumer unit. They are designed to quickly trip and interrupt the supply to the circuit they are protecting, when an imbalance is detected between the neutral and live in the case of an RCD, or when there is a current in the earth wire of the protected circuit, above a preset limit (usually 30mA), in the true ELCB. You can also purchase �plug-in� ones, ideal for mowers, vacuums, and hair dryers, and an RCD plug (replaces the plug), for things like shower pumps. For an excellent article on how an RCD wor ks, see the TLC ARTICLE. Although the primary protection is the fuse in the plug, these do not blow for some fault conditions, and they are there mainly to protect the wiring and the appliance from overloads. To protect the user from shocks and earth leakage faults, the RCD is ideal for this.

Q: My RCD on the consumer unit trips out, what do I do?
A: If this is a solid fault (i.e. it won�t reset), it is most likely due to a faulty appliance that is plugged in all the time, but has developed a fault that is creating a current to earth, or a current in the live not all going though the neutral part of the protected circuit. Most likely culprits are the washing machine, dishwasher, or dryer. Try unplugging each one in turn, until the RCD holds latched in the ON state. If it is not one of those items, and your Freezer is also on that circuit, try unplugging that too. If that is NOT the problem appliance, do not open the door , get an extension lead, and plug it into another room plug as a tempor ary measure (on a circuit not affected), until you locate the faulty appliance. Other culprits can be a kettle, or steam iron, (usually anything that comes into contact with water!). However, don�t for get that even small things like radio alarm clocks, and plug-in timers, chargers, and mains adaptor s can cause the RCD to trip out, so go around and check ALL your items. If you still cannot find the problem, call in a professional tradesman.

Q: How do I change a lamp pendant or ceiling rose?
A: Firstly ensure all power is off to the lighting circuit you are dealing with. Unscrew the ceiling rose cover, and remove the old pendant fitting. In case the wiring is different to that shown in the diagram, make a note of it. Note also that the new wiring colours may now be used in new houses, as the IEE have released an emendment to the BS7671:2001 (IEE Wiring Regulations) in March 2004. The wiring in the ceiling will be either 1.0 or 1.5mm flat twin and earth suitable for lighting. See http://www.iee.or g/cablecolours for an article on this. TLC also has some excellent infor mation about this, at: http://www.tlc-direct.co.uk/Technical/DataSheets/Cable/Index.htm The new fitting (chandelier etc) may not have room, or cover the existing base, so if it has to be removed, carefully rewire all the existing wiring into an appropriately sized connector block, following the cor rect wiring scheme. If this is a bedroom or landing fitting, you may find it easier to fit a junction-box in the loft, just near to where the fitting will be then connecting up with a single piece of twin and earth.
