Purchased an Intermatic mechnical timer P104) to operate my pump and salt generator which are wired together to the same circuit breaker. Electrician has wires for both running into one junction box and then one wire running from there to the breaker panel. Need some help or direction in getting this thing connected. I am fairly experienced electrically but unsure how to properly connect this up. Any help would be of great service. Is this timer a good idea or are there better or simpler units out there. Tired of running out to the pool shed in order to turn everything on and off.
