    Q:Is this 120 or 240 volt? I need 240

    Answer This Question

    A:  This confuses a lot of people understandably. So let me try to add some clarity. This float switch will handle 115 or 230 volts up to a max of 13 amps. However it comes with a 120 volt only "piggy back end" so in a 120 volt application you would plug the float switch into the outlet and then plug the pump in to that. So when the float switch rises it will allow current to go to the pump. Meaning the end of the float is Male by Female. If this float is going to be used in a 230 Volt application you would cut the male by female end off. As there is no such thing as a 230 volt piggy back plug. At that voltage everything would be hard wired. And typically there would be a panel controlling the pumps. When I have laid out these systems in 230 Volt I have done it as follows. The panel receives a 230 v feed and a separate 120 v feed. The 230 supplies the pumps and the 120 supplies the panel. By having two power supplies the panel, alarm still run when the pump burns out. In duel pump systems it is also a best practice to give each pump its own power supply. That way the other pump will still work when one burns out.

        A:  Increasing the the distance from the switch to the clamp increases the depth when it switches on and off It will run a little longer but wont run as often (cycle)

        Using as kill switch for koi pond pump. If water level drops too low due to failure of waterfall tubing connections, pump will turn off before pond runs dry, thus protecting the fish. Tested switch and preliminary indications show “should” function as planned.

        The HD listing says the switch is rated for 1/2 - 1 HP. The UL cord tag says 1/2 HP max. . I returned it to nearest store. I needed it for a 3/4 HP sump pump. Might have worked, might have burned up!!
        Response from chrisOct 26, 2016
        You are correct. I am sorry for the inconvenience and I will correct the listing. Just to offer an explanation as to why this occurred, I checked the Little Giant specification sheet. It does indicate that this float switch will work on pumps from a 1/2" HP -1 HP, but if you look at the specifics you see that it depends on the voltage. The unit is rated to 1/2 HP at 120 Volts and is rated up to 1 HP at 240 Volts. This explains the error but in my opinion does not pass the logic test as you would never run 240 Volts through that style of plug. So I am left thinking, although I may be proven wrong that there is a flaw in there publication. I have a call into them to point this out. We appreciate your feed back because it helps us improve the experience for others going forward. Again I am sorry for the inconvenience.
