TVS is what kills them. I use a a whole house protector on my pool subpanel and a MOV on the motor.

I agree that voltage spikes, dips and transients are the biggest enemy for electronic and motors. Adding some type of protection will save you in the long run.

What an excellent idea - I have the solar subpanel protected but never thought about the pool subpanel. I put in a Pentair Intelliflo XF 3HP in 2014 as part the initial pre solar energy reduction - works perfectly and cut my summer electricity bill by about $80/month with careful programming. I have an extra Square D QO2175SB not being used but not sure there is room for that - time to pop off that Pentair subpanel case and see what its insides look like.
