• Every 300 feet in lightening prone areas
In lightning prone areas, install a surge arrestor every 300 feet on the 2-wire path and at the end of any 2-
wire brand longer than 50 feet.
• At the beginning and end of a long run without 2-Wire Devices
For long runs of wire without any 2-wire devices, place a surge arrestor at the beginning of the run and at
the end of the run. Do not splice the wire run in order to install a new surge arrestor if there are not
devices. Example: valve box 1 is 2,400 feet from valve box 2. There is nothing in between the valve boxes.
Install a surge arrestor after valve box 1 and then just before valve box 2. Do not install any surge arrestors
in-between.
• Install grounded surge arrestors at every “dead end” that is 50 feet or longer.
Below is a wiring diagram for a 2-wire controller system.
