Question for u electrically minded guys

[BLewis]

My Mytee supply pump went down last week do I was going to install my floJet backup. Can you tell me how to wire the 2 wires that come out of the switch? I assume that one will wire into hot and the other to neg but don't want to try it in case it is wrong. I test wired the pump up and it's good to go just need to know what to do with switch wires

Black is usually positive, white is negative, green for ground.

The wires coming out of pump are both black , that's why I'm stumped

 

[BLewis]

Not pump but switch . The pump is orange snd black so I hooked orange up up pos

AC or DC?


We've got no room for boring.

The switch is in series on the + wire.

Thanks Lee...now explain how to hook this switch for an idiot

You are NO idiot, everybody has to learn the first time.

It's convention for the switch to be on the hot + wire, it would usually work either way.

In it's simplest form you would tie one wire from the switch to the + wire of the pump, leaving the other wire (-) alone. Now you feed the supply hot + wire to the second switch wire.

The switch thus just opens or closes the path for juice to the pump.

Billy;

It has two AC power leads.

One goes directly into the motor.

The other goes to the switch, and then to the motor.

The 3rd green wire is the equipment ground.

Ok, got it and it works! Thanks Lee
one more question, the inline safety fuse does it matter where I put it?

 

[dgardner]

If you tied the incoming hot to one of the switch wires as Lee suggested, disconnect it and put the fuse there. So: incoming hot to fuse, fuse to switch wire.

The general idea is that the hot hits the fuse first, so that a short to ground anywhere downstream of that will pop the fuse and thus be protected.
