Description / Abstract:
The general information in this Guide is applicable to all forms of outdoor metal-enclosed switchgear. Specific data are given in Figure 2 for outdoor metal-clad switchgear.* The many combinations of sizes and ratings in similar housings make it impractical to provide equivalent information for outdoor low-voltage metal-enclosed air circuit breaker switchgear. Data are not yet available for specific recommendations on outdoor cubicle-type switchgear, isolated phase bus, outdoor power circuit breakers and other switchgear equipment or components.
