first of all, unplug all the appliances from whole property sockets and try to reset the RCD if RCD reset back then you don't need to go any farther and please leave us your feedback on this website link but if RCD does not reset than you need to investigate more if you are an electrician and you are reading this text then you can understand next paragraph if you are not qualified electrician then you should call an emergency electrician who can come and sort out this problem on 02034881842

RCD stands for residual current device always this have 2 poles one is for live wire and another ball is or neutral wire a single-phase connection RCD is comparing current of live and neutral wires all the time if any of the wire's current is not equal to each other's it means live and neutral parts of RCD will sense it and that will cause the RCD to trip so single-phase and three-phase RCD work in the same manner in single-phase one wire is comparing to another but in three-phase 3 live wires are comparing to one neutral wire so it means what all current which current is going into the system it should return back but not the voltages actual energy is stored in voltages but the quantity of the current stays same so that's why the returning current should be equal to the entering current so RCD helps to detect any leakage current into the system so

what is the benefit of an RCD? and why do we use RCD?

The main reason of using an RCD is to protect the user from electric shock in most of the cases if RCD is tripping due to the sockets then it means there is some problem inside the ring main or the Spur or the radial circuit of sockets it means that at some point into the ring main live or the Neutral wire is touching to the earth wire so because in the actual  earth is a second potential difference point to live that is why the current flows towards the earth that is  why the entering current is not returned to the Neutral wire that's why the RCD sensed the difference and so that made the RCD trip if that is not the case then RCD device is not installed correctly it means of your one of RCD wires are going into another RCD part 

How to fix if fusebox is tripping?

If You come to your home or if you are sitting in your home and you see that your fuse box is tripped or it's being tripped then first try to see on part of the fuse box which keeps tripping and then you will be able to see three different types of devices on your fuse box first will be the main switch which will be like 100 amp DP switch and there will two RCD  into your consumer box and rest of it will MCB and each device is serving different functions like the

Main switch

that is to switch off your main supply

RCD

is it protects you from electric shock and it's tripping just because your insulation of the wire is removed or damaged or one of your appliances is making your RCD to trip

so for example if any of the live wire comes in contact with your metal parts or any of your appliance metal body comes live just because all the appliances and the metal parts are bonded with earth wire due to that earth wire receives a voltage so that RCD senses that some of your metal parts are electrically Live and some current is leaking from metal parts so that it trips to protect you from electric shock so try to unplug all the appliances into your house and try to reset your RCD and it will help to solve your problem if that doesn’t help turn off all the MCB and turn on the main switch and both RCD you will be able to turn on now turn on MCB one by one make note which MCB is tripping the RCD leave that off and turn on rest of it now you need an emergency electrician to fix that problem permanently

MCB

helps to protect your wires from overheating during a short circuit  so for example, if there is any short circuit into your house your MCB will trip if your appliances are overloading your system then it will trip as well try to unplug all your appliances from the sockets and then again try to reset that MCB and if that works then it's fine but if it's still tripping then you need to call an electrician immediately because it can be dangerous for your house and your property and your life and your family's life

Why my cooker, dishwasher, oven, fridge, freezer, iron, washing machine, microwave, hob, extractor fan, kitchen hood, boiler, underfloor electric heating, appliances tripping electric?

So all appliances which are made of the metal body all the appliances are connected to the earth wires as well so if anybody is working and if your appliance metal body is not under an influence of voltage you're RCD will not trip but as soon as your appliance metal body receives a voltage then it will cause the RCD to trip to protect you from an electric shock so try to disconnect that applies and try to turn on your electrics again if the fuse box RCD allows you to turn on then it's fine and discontinues that appliance but if it doesn't work then there is some problem inside your wire so you need to call an emergency electrician to sort out this problem  

when It comes to fuse box repair and consumer unit repair most of the time problems are related to RCD repair normally RCD trips due to power plug sockets and that type of fault effects all the lights and blubs sometimes lights flicker in property that is not due to RCD fault that is the reason of lose connection if that is happing in your property then you should get it checked by certified electrician and ask them to carry out one EICR which stands for Electrical Installation Condition Report and that EICR will be carried out according to the current UK regulations BS 7671 that is Wiring Regulation and latest regulations which are released in 2018 your whole property must comply with 18^th edition here are some EICR codes meanings which can help you identify problems first one is C1 = Dangerous and Immediate action needed 2^nd one is  C2 = potentially dangerous and action needed urgently 3^rd one is C3 = improvement required if there is any problem and last one FI means  = future investigation needed urgently most of the EICR problems originates from the unsafe fuse box which should be upgraded to RCD protected metal consumer unit that consumer unit will protect you from any potential electric shock some times EICR fails due to wiring condition and wiring condition means condition of the wires insulation is not good and insulation resistance is low the resistant means condition of the wires is bad on the other hand higher the insulation resistance means good condition ideally insulation resistant should be infinite at 500 Volt DC test if insulation resistant is continually low then it means your property needs a rewire but it is always best to get an electrical safety certificate before doing any upgrades or replacements in electrical system most of the time kitchen is very important area of you house or property most of the times kitchen fuses are blown or kitchen breaker or MCB trips due to any faulty appliance in the kitchen if that happens with any appliance please you should unplug your appliances switching them off is not enough because if you are  switching only live wire will get disconnect neutral and earth wires don’t get disconnect so you need to unplug all of your appliances and then try to turn on your RCD it will turn on if there is no fault in wires but if there is any fault then you will need an electrician
