My wiring diagram for current sensing relay

I keep the dog from chewing on wires by not having a dog.

That’s a terrible solution!

Well this thread certainly has taken a techie turn.

The nochew9000 is going STRONG, thanks. The wire is ziptied under the pipe the rest of the way where they leave it alone.

On a sort of related topic, I’m starting to think that I might need a larger (or second) breaker and wire running to my panel. The pump is rated to pull 16 amps, plus the heater, lights, and now SWG. I think everything is on a 20A breaker with I’m assuming 12 gauge wire. Gotta check wheni get home. How many amps does a SWG actually pull?

How many amps does a SWG actually pull?

Depends on the SWG "size" (15, 20, 30, 40, 60) and the voltage (120 or 240). So you'd have to find your units spec's in its manual and then do some math (you haven't listed your SWG in your siggie yet).

The power supply for my SWG is rated at 7.5A max, so my IC40 draws less than that. Not much to go on, but that's a ballpark.

My pad is on a 30A breaker and sub panel, and that also powers a myriad of yard lights and fountains and gizmos. 20A does seem a little thin, especially for future expansion.

I need constant supervision. I am not qualified to operate another being. My brain is having trouble with just the one!

I like dogs, but believe me, I'm being kind to them with this solution.

What happened to the other 8,999 prototypes? Lemme guess...

I did some digging, and the 7-8 amps is only at the low voltages (about 24 v) cell. At 220/240 volts, it looks like it only pulls around 1 amp from the panel... so I'm good to go! I have enough headroom to run the SWG on the existing circuit.

Sorry, I didn't answer that well. How many amps the SWG itself pulls vs how many amps its power supply would tax your breaker would, of course, be very different numbers.

I’m always confused, no matter how well you answered me!

The relay is adjustable on how many amps will trigger it. I can dial it in so it only closes when it reaches the amps pulled by my pump at its minimum RPM. Any tiny amount of amps being pulled will be below the threshold I set.

Oops! Actually, looking back at the start of this thread, you said that!
