The problem with mission-critical emergency systems is that failures only occur when the systems are called upon to operate. Comprehensive electrical maintenance does not preclude a failure; however, it dramatically increases the odds that a problem can be detected and corrected in advance. The problem with electrical safety is that folks rarely realize the potential consequences until after an incident occurs. Don’t allow your employees, contractors, or business to become another statistic.
The electrical environment in modern mission-critical spaces can be very confusing, to say the least. Typical voltage distribution configurations include 575 volts (V) 3Ø, 480-V 3Ø, 208-V 3Ø, 208-V1Ø, and 120-V 1Ø. 415-V 3Ø/240-V Ø1 is gaining popularity due primarily to elimination of transformers at various points. Proposed high-voltage direct current distribution presents a whole new set of challenges. Regardless of what configuration you’re dealing with, proper over-current protection is required.
