Installation

GENERAL:
1) Always follow good N.E.C. (C.E.C.) grounding and bonding wiring procedures. 2) Use ‘approved’
insulated ring terminals for all wiring connections. 3) Use # 14 or # 16 AWG, type MTW or THHN
copper wire only.. 4) Wiring must be rated higher than nominal voltage and temperature values
anticipated in installation.
INSTALLATION: 1) During installation orient the fitting so the tapped hub on the terminal housing
faces the most favorable direction for receiving the conduit from the control box. 2) After conduit
has been installed and conductors pulled through same, fasten the incoming ground conductor(s) as
shown below; the ground connection should be facilitated by securing that end of the system ground
wire to one of the four screws provided which hold the terminal housing to the body of the electrode
fitting or to the ground screw when provided.
