If replacing, go to a proper electrical supply and ask for a
switch with a "HP rating" at least as big as the pump HP rating.
I got it at Ace, but if this was goes South, I'll try that the
next time. I got this message after doing all the work. ALso, the switch
I got is pretty the same one and the what I took out when the pool
people replaced the switch about 5 years ago.
On the original and/or replacement, examine the switch very carefully.
It may have voltage/amperage and voltage/HP ratings listed on it.
The "better" quality switches you should be using often have them
stamped on the switch or a label.
I've "re-purposed" some industrial heavy duty relays/breakers/switches my
dad tried to throw out out many years ago, and they all had HP ratings
listed on them -
The radio control switch (good only to 600W incandescent ;-) powers my 1HP
dust collector thru a relay that's rated for 15HP motors on 600V ;-)
Being a Canadian, I don't know Ace hardware, but if they cater to farmers
& their requirements as I suspect, it may well be the proper switch. If from
the automotive section, probably not ;-)
