Checkyour local codes and regulations for other recommended clearances.Table 1.

Plan the cable routing and conduit access to the cabinet: The top and bottom of the cabinet have swappable entry plates andremovable plugs for cable connection. See Figure 2 on page 11. Identify all conduit requirements and mark their location. To avoid congestion and allow for future load increases, use the conduitopenings closest to the center of the cabinet first. Bottom entry wiring. To allow for proper bending radius and ease of installation,for ground and neutral connections use the conduit openings farthest from theconnection. Size conduit to accommodate one neutral conductor the same size as thephase conductor and one ground conductor. If two neutral conductors or anoversized neutral conductor are to be installed, size the conduit toaccommodate the extra wire or size. All PDR products can accommodate adouble−sized neutral.
