Control System Installation and User’s Guide
Installing Conduit and Wire to the Power Center
• Use No.14 minimum to No.6 maximum AWG for power relay circuits depending on the power
requirement. Be sure to follow all regulation safety codes for the number and size of conductors that
can be installed in various sizes of conduit.
• Supply circuit must be protected by suitable circuit breaker.
• To avoid obstruction into the SunTouch
®
Control System Power Center, when using electrical
conduit complete the installation of the conduit before concrete is poured. Also, underground
conduit should be positioned in well compacted soil. Ensure that all conduit joints are well sealed
and watertight.
