i know what the contacts are it's the circuit i'm stuck with. i can't draw it as i don't understand it :)

i'm so confused :(

Hi, I'm working on a small project and need some help with relay wires. I have two relays that get turned on by different items but i need both relays to be able to turn a third relay on when one of them gets activated (the third relay powers a sounder) i then need for the third relay to be...

Its for a 24v control circuit that will power panel lights, timers and contactors etc

would a quick blow glass fuse be better?

I was told to use normal type B

I am working on a small project and need to fuse two outputs at 24v DC (2A) and 12v DC (2A). A panel building friend of mine has told me to use MCBs at 2A each but in my tests the breakers had no tripped at 2.9-3.1A and they were getting quite warm. I would like your input on the best fuse...

Thanks for all your replies I will give them a ring and see what they say. I have actually never had any problems from it apart from standard bulbs lasting about a week tops but since I have moved over to LED everything I have had no problems with blowing bulbs.

Hi, I was repairing a broken socket front yesterday in my house and noticed that at every point including the consumer unit the incoming voltage is 257-260v (fluctuates) is this acceptable or do I need to call northern power grid? Thanks

why are fuses used compared to breakers?

its the only picture I could fine, the question is about the switch fuse versions like a 20A one or 32A one.

Im curious, when an what applications are these used for and whatare they not suitable for?

If im not mistaken siemens had the same design for one of their breaker range?

While looking for a B16 MCB the other day I stumbled across a B13 and C13 MCB made by various brands... what would they be used for? it seems an odd size??

Sorry for the lac of info guys, the battery will be two 10AH 12v batteries wired in parallel to up the amperage (not car batteries as stated before). I will need to run about 200w from it all in total.

Hi, I want to charge a car battery via a solar panel connected to a solar charge regulator. Form this it will connect to an inverter to power some mains items. What size solar panel would I need to successfully charge the battery and it not take weeks to do so? Thanks

Your picture shows that you have not connected the neutral cables to the fittings only live in both terminals.

Nope all done, in the end we have opted for a new supply from YEDL
