New SWG Install - Power cord?

[ajw22]

Paddle switch existed before I bought the house, when the circuit went all the way to the main panel, and the timer was located inside. When I added the sub panel and heater, I had the timer located outside as well. However, the paddle switch is still super convenient because it's right next to the pump, filter, and SWG. The timer is on the opposite side of the fence next to the sub panel, and heater.

Got it. A legacy issue of multiple "improvements" over the years. It grows to confound new homeowners over the years.

What's the reasoning against putting both the pump hot and SWG hot on the same contact in the timer?

The paddle switch is downstream from the timer. If you connect the SWG to the timer hot it will still be powered when you turn off the pump using the paddle switch. SWG has to be connected to the same switches as the pump ... the paddle switch.

By the way, thanks for all your help. I've learned a ton in the past 24 hours.

Happy to help and watch the light bulbs turn on.
