Electrical Safety for Construction and Manufacturing: Best Practices

At the crossroads of construction sites and industrial facilities, one paramount concern takes center stage – electrical safety. It’s not just a priority; it’s a non-negotiable imperative. The very first order of business in this realm is a meticulous examination of the voltage and phase prerequisites for the job site or facility. This meticulous scrutiny is a linchpin in averting potential damage to equipment and, more critically, the prevention of harm to untrained personnel. In this pursuit of safety, partnering with a certified electrician when deploying portable power solutions is an absolute must.

Transformers: The Foundation of Electrical Systems

If transformers are part of the equation, there’s no room for guesswork. Ensuring the proper vector configuration is in place for the electrical system is paramount. In the context of a manufacturing or industrial plant, you often have experts on hand who can provide this crucial information. However, in the dynamic world of construction sites, where contractors may not be as versed in such nuances, a trusted partner like Unicel Autotech can step in and guide the process. Key considerations when it comes to transformer safety encompass:

  1. Multi-Tap Transformers: If the transformer boasts multiple taps, meticulous verification of voltages and vector configurations on both the high and low sides is imperative.
  2. Phase Verification: Before making the critical connection to the transformer, phase verification is non-negotiable when paralleling a transformer.
  3. Grounding Matters: The transformer must be meticulously grounded, and a qualified electrician should confirm the grounding and neutrals.

Generator Grounding and Distribution

The generator itself is not exempt from safety measures. It should be properly grounded, adhering to the guidelines laid out in the National Electrical Code (NEC) or local electrical codes. Moreover, when it comes to distributing power to multiple areas, this task demands precision and the involvement of a qualified expert to circumvent property damage or personal injury. Understanding the intricacies of electrical distribution design is pivotal. On a bustling construction site with diverse power requirements, Unicel Autotech can provide both the sizing expertise and recommendations to ensure seamless distribution.

Harnessing the Power of Paralleling Generators

Paralleling generators is a strategic move that can enhance efficiency and save space while ensuring a robust power supply. Imagine two smaller 500 kW generators working in tandem to deliver a combined output of 1000 kW, effectively starting a motor on a piece of equipment. Later, one of the generators can be idled, serving as a built-in backup. However, this process demands precision. To safely parallel generators, it’s crucial to match voltage and frequency meticulously. While newer generator models tend to be more user-friendly, they still require the expertise of a qualified technician.

Navigating Non-Classified Areas

In environments like refineries or chemical plants, electrical classification restrictions come into play. When flammable liquids are part of the equation, the generator must be situated in a non-classified area, maintaining a safe distance to mitigate electrical and fire hazards. This relocation often necessitates the use of additional cables and cable management or the ability to safely integrate with the facility’s electrical system.

Training: The Cornerstone of Safety

While the installation of generator power should exclusively be entrusted to qualified electricians or technicians, operators on construction sites and in industrial settings can benefit immensely from proper training. Collaborating with our dedicated team at Unicel Autotech can empower operators to comprehend the nuances of a specific generator model and its operation. This step is pivotal in safeguarding both operators and those in the surrounding area. To further bolster safety, consider measures such as fencing and warning signs.


In the realm of electrical safety for construction and manufacturing, every detail counts. Whether it’s transformer configurations, generator grounding, distribution intricacies, paralleling generators, or adhering to classification restrictions, meticulous planning and expertise are the keys to ensuring a safe and productive environment.
