Thanks, was just curious to know, as I will be adding more devices to the panel, The relays used to be supplied from the panel but the issue with that is not all sounders would activate in the event the panel lost power or destroyed, as they still have a supply from the psu. Sorry to sound daft...

Its just 2 relays btw, one for the bell and the other for the strobe.

Hi all, I set up my alarm system some years ago which has multiple sounders, So obviously I have an additional power supply as the panel could not cope with the total current draw, It all works fine btw, my only question is where the current is being drawn from for the trigger relays, is it...

Hi all, just an update, I had purchased a kewtech loopcheck 107, All my electrics seem to be in good condition and wired correctly after all, the green led loop tes led lights on all sockets, according to manual this means the earth loop is lower than 1.8 ohms, the loopcheck has an rcd test...

I have just tried that trick on my polaroid 32 led tv, I connected the neutral wire in plug to the earth terminal then switched on and to my surprise the rcd did trip, the tv draws about 60w max when running in use, it was on standby so I am not sure how many watts it drew, its just after...

Never thought about that, sounds like a handy trick and very simple, I will give that a go,its certainly sounds much safer than grabbing hold of a live wire me thinks:LOL:

Hi, the rcd trips when the button is pressed that has never changed, its more how it behaves towards the rest of the circuits it supplies if that makes sense, without spending fortunes on the proper testing equipment I cannot see a way to accurately test the rcd whether it will save your life or...

The thing is tho all circuits were on at the time, only small loads were being used however, just your usual fridge/freezer tv and a few lights ect, it used to trip when touching the neutral and earth when the central heating was running, it does not do this anymore which concerns me. I...

Hello again, having done further inspection, it turns out if I touch the neutral and earth together the rcd does not trip at all, I tell a lie it does trip but only when heavy loads are switched on such as the kettle, Do I have an earthing or insulation problem? I heard somewhere that a nicked...

Hi, yes turning off big red switch on the isolator cools it down and neon extinguishes, it is starting to sound like it could just be a resistor heating up when in use for the neon indicator inside the unit. I am no expert but I am sure if it was arcing the unit would be too hot to the touch and...

Hi all, I have fitted british general "BG" Nexus accessories around my kitchen as the old ones where all scratched, the accessories are the low profile type with the screws filed flat with a finishing metal plate to hide the screws. My only concern is the cooker 45 amp isolator switch is warm to...

Like most people, I have never really bothered to test the rcd monthly, I don't know anyone who does? The rcd has tripped in the past where there has been a faulty iron, and sometimes when I accidentally touched neutral to earth when replacing sockets, although touching neutral and earth didn't...

I'm no expert, it could may well be the fault current was so high that the mcb operated quicker, perhaps if the fault current was bit lower the rcd may have operated as well?

Hi all, Yes it still trips when you press the test button, Could it be age?, I'm not sure what to think? I'm thankful the mcb tripped but the rcd not tripping worries me, if it won't trip on such a huge imbalance, how will it behave if you receive an electric shock?, does it need replacing? thanks

Hi,nope, polarity is all correct, no cross connections.

Yes, all sockets circuits are protected by the rcd, its a hager split load consumer unit about 20 years old, only the lights are not on the rcd.

Hi, I was loosening my sockets for decorating and upon loosening one of the sockets there was a loud pop and bright flash and sparks flying in my face, it turns out one of live cables of the ring had slipped out its terminal and shorted against the earth bar. This tripped the 32 amp circuit...

Thanks for clarifying, Not an issue was just curious, It is connected to my scantronic 9600 which I am sure you know is almost bulletproof, I know the 9600 is a very old system and I should get something more modern but tbh its works and has proved reliable, I am yet to see a modern system which...

How the times have changed, the good news is I managed to get another prima 300 which works very well, onboard batteries are healthy, just one question for anyone who has used these, me being technical, I measured the current on the prima 300 on a bench test in full alarm and strobe with the...

I gave them a call, no luck, they said it was discontinued years ago, Shame, Why are we doing away with quality things and renewing with modern crap is beyond me? Maybe I will buy a master blaster, I shyed away because it needs a mains supply which can easily be defeated, and klaxon inferno is...
