Over the past 50 years, it’s been augmented repeatedly with additional power plants and power lines to be able to distribute electricity to the increasing number of end users. But this is both expensive and environmentally disturbing.
Counterfeit electrical products create workplace hazards

Energy efficient LV transformer
Lean Power energy efficient low-voltage transformers reduce energy consumption and costs for end users, while also addressing the impending federal government mandate requiring that all transformers manufactured after Jan. 1, 2007, meet new standards for increased energy efficiency. Features include easy installation as well as a 3-inch clearance from ventilated openings instead of 6 inches, which reduces the distance from the wall to the front of the device by 3 inches.
Include surge suppression in power protection designs
In reviewing the array of power protection options, those responsible often think in terms of products rather than holistic solutions. While that may seem like the easy approach up front — just buy a big uninterruptible power supply and be done with it — most users find that a bit more analysis in the beginning yields optimized equipment protection and better addresses the full spectrum of power problems. Of course a large, centralized UPS system from a quality vendor will provide excellent protection against the widest range of power disturbances for any connected equipment. This is especially true in data centers and other high-density computing or communications environments.
External disconnect enclosure for NFPA-70E compliance
SEQUESTR external disconnect enclosure is designed to help manufacturers comply with NFPA-70E and other regulations. It isolates the fused disconnect switch or circuit breaker from the main control panel while maintaining the door interlocking requirements of NFPA-79, IEC-60204 and SAE HS1738. With traditional disconnect enclosures, even when power is turned off, live power is still present on the line side of the switch, requiring anyone accessing the inside of the enclosure to wear PPE appropriate for the amount of potential incident energy present. Wearing bulky PPE while servicing electrical equipment decreases productivity by increasing service time.
