Hi, anyone got any idea on pricing and a supplier for a wireless contactor. Basically I need to disconnect the pv on loss of grid prior to the generator kicking in. Unfortunately i'm unable to connect on the grid side of the generator set without digging up a trench.
Thanks.

Hello,
My workshop pillar drill is currently controlled at the mains socket so not ideal. I have come across the attached start stop box but unfortunately no wiring diagram. Having looked online the only advice I can find is that the live feed should go through the E stop button. I have had...
I'm not sure if this is the correct place to ask but I'll try anyway.
We're building a room in the back garden that we're going to use as a little home cinema.
We'd like a button next to the sofa that, once pressed, dims the lights to black (taking around 2 seconds to do it), like how it...
