Look at your own property and see how different your electrics are to the above ?
Have you got an earth wire to all the lighting circuits in your property ? if not have you got metal light fitting if you have then you at risk of electric shock at any time an electrical fault shorts to the metal work .
Rubber insulated wiring ( vulcanised rubber ) is not acceptable and needs replacing.
The simple or not so simple plug . Looking down from the top the live wire Brown goes to the right fuse carrier connection. The blue wire goes to the bottom left neutral connection and the green and yellow earth goes to the top earth pin connection. Simple or is it?
Typical under floor junction box unless you know what you are doing i think left well alone call in an electrician or even ourselves . This is when things really start to go wrong . Electricity is not your friend it Bites
This what electricians deal with all the time its like another language unless you know what you are doing DON'T
RCD Problems can leave you with lights working but no sockets read on
A residual current device (RCD), or residual current circuit breaker (RCCB), is an electrical wiring device that disconnects a circuit whenever it detects that the electric current is not balanced between the phase ("hot") conductor and the neutral conductor. Such an imbalance is sometimes caused by current leakage through the body of a person who is grounded and accidentally touching the energised part of the circuit. A lethal shock can result from these conditions; RCDs are designed to disconnect quickly enough to mitigate the harm caused by such shocks.
In the United States and Canada, a residual current device is also known as a ground fault circuit interrupter (GFCI), ground fault interrupter (GFI) or an appliance leakage current interrupter (ALCI). In Australia they are sometimes known as "safety switches".Purpose and operation RCDs operate by measuring the current balance between two conductors using a differential current transformer. The device will open its contacts when it detects a difference in current between the line conductor and the neutral conductor. The supply and return currents must sum to zero, otherwise there is a leakage of current to somewhere else (to earth/ground, or to another circuit, etc.).
RCDs are designed to prevent electrocution by detecting the leakage current, which can be far smaller (typically 5–30 milliamperes) than the currents needed to operate conventional circuit breakers or fuses (several amperes). RCDs are intended to operate within 25–40 milliseconds, before electric shock can drive the heart into ventricular fibrillation, the most common cause of death through electric shock.
In the United States, the National Electrical Code, requires GFCI devices intended to protect people to interrupt the circuit if the leakage current exceeds a range of 4–6 mA of current (the trip setting is typically 5 mA) within 25 milliseconds. GFCI devices which protect equipment (not people) are allowed to trip as high as 30 mA of current. In Europe, the commonly used RCDs have trip currents of 10–300 mA.
Residual current detection is complementary to over-current detection. Residual current detection cannot provide protection for overload or short-circuit currents.
RCDs with trip currents as high as 500 mA are sometimes deployed in environments (such as computing centres) where a lower threshold would carry an unacceptable risk of accidental trips. These high-current RCDs serve more as an additional fire-safety protection than as an effective protection against the risks of electrical shocks.
In some countries, two-wire (ungrounded) outlets may be replaced with three-wire GFCIs to protect against electrocution, and a grounding wire does not need to be supplied to that GFCI, but the outlet must be tagged as such. The GFCI manufacturers provide tags for the appropriate installation description.
No power, lights working but power sockets are not. Unplug all appliances from the wall sockets, unplug not just switch off.make sure and external devices are unplugged pond pumps extension leads etc. Then switch into the off position all the fuse box trips. Reset the rcd breaker this normaly switches the opposite way to normal breakers and then switch back each normal trip until all the power is back on, should one of the breakers cause the RCD to trip then leave that breaker off get power back on to the rest of the building. If all the power comes back on then plug individual appliances back in should one of the appliances trip the RCD then you have found the problem. This process can take a while so be patient. If all else fails then you will need professional help so give us a call on 01162333666
