Level 4 Power Circuits
AĆC and DĆC buses up to 1000 V with currents up to 800 A (Class 4S for power greater than
1000 V and/or 800 A.)
The installation wiring for these levels must be physically separated to prevent poor system
performance as a result of induced noise. Within each level there also may be classes that require
additional grouping and separation of installation wiring. These levels and classes are defined in
ANSI/IEEE Standard 518, Section 6.4.3.1.
