I have a switch which powers a small compressor for a Biodigester (waste tank). I have bought a timer that can be wired in but I'm having trouble working out the wiring.
There is a fused switch and my intention is to put the timer in between the fused switch and the compressor.
In the timer there is a block with four spaces. The diagram for the timer switch shows
1. Live output to appliance
2. Make link with a 1.5 sq mm wire to switch 240Vv AC ONLY. Should you wish to switch other than 240v AC do not use link to terminals 2&3. Feed the required switching voltage to terminal 2 and output from terminal 1.
3. Live from mains
4. Neutral from mains.
Can anyone help with the following......Numbers 1,3&4 are simple enough. Should the neutral to appliance be in 2 and then a link between 2&3? Should I connect the earths to a nearby water pipe ? (There are already earths connected to the pipes).[/b]
