Be sure the wire is between rows of
sprinklers and away from other
wires, pipes, etc. as far as possible.
This will place the wire in an area
that will be frequently watered and
will increase the surface contact of
the grounding network.

In the center of the triangle, of the 3-
rod grid, install an 8’-0” long piece
of 6” diameter perforated plastic
pipe. Top shall be at least 6” below
the finish grade. Fill this pipe with
rock salt, Epson salts, or other
suitable similar material and water it
down. The salt will leach out into
the soil and corrode the surface of
the rods giving improved and greater
surface contact. Place a 6” diameter
valve box cover over the end of the
pipe and cover it with soil to finish
grade.
MSP-1 PIPE SURGE ARRESTORS:
Each of the pairs of wires in the
communication path, between the
central computer and the weather station,
shall be wired through an MSP-1 pipe
surge arrestor, at both the computer end
and at the weather station end. The
MSP-1 pipe surge arrestors shall be
located as close to the equipment it is to
protect as is practical. The MSP-1 pipe
surge arrestors shall be mounted in
MGP-1 grounding plate assemblies.
The MSP-1 pipe surge arrestor is
marked, “EQUIP” on one end and
“LINE” on the other end. When
installing the MSP-1 be sure that the end
marked “EQUIP” is located “toward the
equipment” it is to protect, i.e., computer
or weather station. The “LINE” end
goes toward the field.
The Green wire on each end of the MSP-
1 pipe surge arrestor shall be attached to
one of the grounding screws on the
MGP-1 grounding plate assembly.
