Installing a mechanical timer on a swimming pool?
I have an inground swimming pool an every nigth i have to go outside to turn the pool filter on, so this year i went to home depot and purchase a Mechanical timer model T101 intermatic ,i'm trying to install it my self but Iam having a little problem. Do I remove the switch from the pool filter? or do I need to run a new wire?

Your power line to the pump has a hot wire, a nautral wire and a ground wire.
Take the power line from the panel and connect it to the line and neutral terminals. Connect the wire going to the pump to the load and neutral terminals. Connect the grounds to the timer as well.
Your existing wire may not be long enough to cut and add this timer, so you may need additional wire. Remember, outdoor pools require individual wires in conduit. UF is not allowed.

I just bought a T101 also but I want to have it next to my service panel.
I am running a 20 Amp GFI to box.
I understand how to put the GFI and plug and switch in. I do not understand the Timer.
Starting from the outside switch to plug then (timer to box) or (box to timer).
Do I run the cable to the timer first then into the box or Do I run the wire to the box and then to the Timer which does not make sense to me?
Thanks,

In theory, you could run the wire either way, except that you would need an extra conductor if you for the timer if you don't wire through it, because it needs a neutral.
However, I do not recommend making splices in the main panel, especially with a GFCI involved as it increases complexity.
Wire from the panel to the timer and then to the pump motor.
