i'VE JUST INSTALLED A NEW RING CIRCUIT INTO MY HOME. pROBLEM IS MY RCD KEEPS TRIPPING OUT WHEN I HAVE THEM ALL ON AT THE SAME TIME. THE CIRCUITS IN MY WORKSHOP. SHOULD I JUST REPLACE THE 32A MCD TO A 45A INSTEAD. OR SHOULD I REDO ALL MY TEST AGAIN?
 
RCD or MCB???

If it is the MCB, which I tend to think it is, you are overloading the circuit.

You must not increase the rating of the MCB. Your cables would overheat!!

What do you have plugged in, and what gets used at the same time??

I suspect you should have planned a little better prior to installing the ring circuit.

1: stop shoutin
2: all of what on at the same time?
3: why would replacing a 32A MCB to 45A stop an RCD trippin.
4: whats trippin? RCD or MCB? if RCD you have an earth fault. if MCB, your overloading it. changing the MCB to a higher rating will cause a fire
5: if it was planned better and tested properly you would not have this problem
 
tHANKS FOR REPLYING I MEANT THE RCD KEEPS TRIPPING OUT THE CIRCUIT

My workshop is full of computers I build and sell them for extra income. anyways thats what I'm using the sockets for.
In designing the ring circuit. I counted up the maximum devices that I would be using. And took that into consideration on my cable calcs.

WOULD IT BE AN IDEA IF I JUST REPLACED A DOUBLE SOCKET PLATE WITH A DOUBLE BLANK PLATE?

This way reducing the possibility of overloading the circuit

computers. im assuming you know about the special rewuirement of earthin? how many computers do you have?

you are NOT overloading the circuit. the computers leak current to earth (NOT a fault) but too many computers and the earth leek exceeds 30mA, tripping the RCD
 
sorry i did'nt realise that capitals meant "shouting". I'm not the best typer in the world

I really do appreciate you guys taking the time out

so how many computers do you have and how many sockets? what does the RCD protect? just sockets?
 
I'm sorry I don't. How can I reduce the the 30mA level to prevent the tripping?

Thanks

connect less computers. the only way. only other option is to use RCBO's instead, and have 2 (or even 3) ring mains for power. and surely youll kno how many computers you have. until we kno, we can only guess what you need to do
 
The RCD just protects the sockets.
The lighting circuit is separate 4 luminaires

I have at any one time 16 - 20 computers being built

if i remember correctly, a computer leaks 4-5mA. so you have to have 6 max to stay under 30mA. try switchin on 1 every 5 mins and c how many are needed to trip the RCD. best option would be to use RCBO's and have 2/3 circuits. also, are the lights on the RCD side? unless you have a TT supply, then they should be on the non-RCD side
 
You require high integrity earthing.

You also should remove the rcd from the sockets on your test bench, and provide some rcd protected sockets near the door for use outside.

putting a blank plate will not make a difference if you have an earth fault. If you overload the circuit, as said before you must know the load you putting on the circuit, and whether there is something else that connected to it, may be some electrical tools except the PC's?
 
I have a tn-s system power supply. so with the socket problem being an earth fault woul it be best to replace the RCD with an RCBO?
