NOTES:
1. 400-Hz SOURCES INCLUDE POWER DISTRIBUTION PANELS, MOTOR GENERATOR SETS, MOTORS,
TRANSFORMERS, CONTROLLERS, AND EQUIPMENT CABINETS.
2. 60-Hz SOURCES INCLUDE POWER DISTRIBUTION PANELS, FLOURESCENT LIGHTS, MOTOR
GENERATOR SETS, MOTORS, TRANSFORMERS, CONTROLLERS, AND EQUIPMENT CABINETS.
3. SEE PARAGRAPHS 6.7.3 AND 6.7.4 FOR SPECIFIED FLEXIBLE METAL CONDUIT AND RIGID METAL
CONDUIT RESPECTIVELY.
4. EXAMPLE OF CHART USE: A SUSCEPTOR CABLE HAVING THE DESIGNATOR S4-1, AND SHIELDED IN
FLEXIBLE METAL CONDUIT IS TO BE ROUTED NEAR A 60-Hz POWER DISTRIBUTION PANEL. THE
INTERSECTION OF THE “S4-1” COLUMN AT THE “60-Hz SOURCES-FLEX CONDUIT” LINE INDICATES A
SPACING OF 3 INCHES.
5. SPACING REQUIREMENTS SHOWN ON THE CHART ARE GIVEN IN INCHES AND ARE MEASURED
FROM THE OUTER SURFACE OF THE SHIELDING CONDUIT OR CABLE TO THE NEAREST SURFACE
OF THE INTERFERENCE SOURCE. (SEE FIGURE 6-9).
