Selecting the right power cable may seem like a routine decision, but in reality, it holds significant consequences for the performance, safety, and efficiency of your entire electrical system. From small commercial installations to large-scale industrial projects, one oversight in cable selection can result in system breakdowns, project delays, or even fire hazards. This guide highlights the top five mistakes professionals often make—and how to avoid them.
Choosing a cable without considering the voltage rating and load capacity can lead to overheating, power loss, or equipment failure. Always assess the maximum current, voltage level, and duration of load cycles to ensure the cable matches your system’s needs.
Cables exposed to moisture, chemicals, heat, or mechanical stress need specific insulation and protection. Ignoring these environmental conditions can cause premature damage. Choose cables with features like UV resistance, waterproof sheathing, or armoring for harsh environments.
Unbranded or uncertified cables may not meet safety or performance standards. This can result in frequent failures, fire risks, and non-compliance issues. Always look for industry certifications such as ISI, BIS, or IEC to ensure reliability and safety.
Selecting a cable only based on present usage can be short-sighted. If the system expands, inadequate cable capacity may require reinstallation. Choose cables that offer extra headroom for future upgrades or increased electrical loads.
