Gentlemen:
Thought I would drop this out here for help.

Anyone have advice on if A REMOTE (second)HOA switch can be installed?
25HP transfer pump (water) that is 1600' from the second location.

VD situation is already addressed.

John,
You have two problems to deal with; voltage drop and capacitance. The voltage drop could keep the starter from pulling in and the capacitance could keep it from dropping out when you turn the HOA off. Look at this site: http://www.squared.com/us/products/nema.nsf/DocumentsByCategory/114F29214C232A6A852568390055A15D

If you are going to have switches in two different locations, it is probably easier to use momentary ones wired in parallel. Each switch pair would then turn on a control relay for "Hand" or a different one for "Auto". This will be much easier and use less wire than trying to do with maintained pposition switches.

Definitly evaluate the website Don directed you to. Even though it is for Square D products most vendors have similar coil characteristics so the tables should be interchangeable.
