MCA = Minimum Circuit Ampacity.
Maximum Overcurrent Protection (MOP) is calculated as follows: (Largest motor FLA x 2.25) + (Sum of
other motor FLA) rounded down to the nearest standard fuse size.
• Measurement taken 4.92' above finished floor, and at a distance of
3.3' from face of unit.
• Measurements taken with no attenuation and units operating at full
load normal operating condition.
• Sound level will vary depending on a range of factors such as
construction (acoustic absorption coefficient) of particular area in
which the equipment is installed.
• Sound pressure levels are measured in dB(A) ±3.
• Tested in anechoic chamber per ISO Standard 3745.
