so the relay is switching the mains rather than the float switch

Hi Thats it its so you dont have 240 volt going through the float as i think John said it would burn the float out. HTH Eric:D

i presume it also means keeping 240v away from the water i,e, the float switch....which can only be a good thing :D

LOL but your pump is still mains voltage, as is the rest of the kit in your tank, there are float switches on the market that will switch over 1kw.(1000 w)

Hi Richard thats true m8 , but i think the trouble was putting 240volts through a floatswitch that was not rated to take that amount of power. HTH Eric:D

You dont want home made connections running 240V anywhere near the salt water IMO.

Unless of course you are a qualified electrician, then you can take the risk whilst knowing the dangers.

hi mate,most float switches if not all will switch over 15w from RS or Maplins, the ATU im using came from kenslovechild from the other bb and he sells them on ebay, i just copied the parts and built myself a spare, 100% perfect , and wired up like your diagrams Eric, but with no transformer.

HE HE bonus for me then, but if you put all connections in a IP64 rated box , you will be safe .
