1.2 Ground Mounting
Although ground mounting the CPR cabinet can be accomplished by several methods, the
following procedure is recommended:
1.2.1 Select an appropriate site. Check with other local utilities for buried plant before site
location is finalized. Remove the turf and level an area of approximately 4" greater
than the foot print of the CPR cabinet. Refer to Figure 1.2-1 for details.
1.2.2 In accordance with local codes, install the disconnect box near the AC power
source.
NOTE: The disconnect box should have a high magnetic type circuit breaker, capable of
passing short duration inrush currents, and have a minimum rating as shown below.
For 120 VAC 60 Hz units, the service disconnect shall be a high-magnetic type circuit breaker
rated for 20 amperes in the line lead only.
For 240 VAC units, the service disconnect shall be a 2 pole, high-magnetic type circuit breaker
rated for 20 amperes.
For 220VAC, 60Hz and 230 VAC 50 Hz units, the service disconnect shall be a high-magnetic
type circuit breaker rated for 16 amperes in the line lead only.
