Industrial electrical control panels fall under two categories:
- Units that contain components that control major industrial production systems, such as presses, cranes, conveyors and refrigeration units or
- Units that contain components that control environmental systems, such as lighting, HVAC and pumps
When power or control components, such as motor controllers, wires, relays and switches fail to work properly, production immediately slows or comes to a halt, resulting in lost revenue and great on-site emergency repair call costs.
Therefore, it’s critical that you hire technically trained personnel to perform regular preventative inspections and repair any equipment if the following conditions exist in your factory.
Power surges, roof leaks and floods are all reasons to have your equipment inspected.
Some factory employees fail to seek assistance when they notice warning signs, such as an unusually warm enclosure, low performance, metal corrosion, component wear, strange smells or noises, even though these warnings often occur before electrocution and fire events. Causes of some signs vary, for example, defective and worn wire insulation and current leaks can cause performance problems and strange odours.
Many factories have custom, D-I-Y patched and junction box control panels designed to fit their unique industry, product and/or environment needs. These units usually have messy and overcrowded interiors that create unnecessary repair and safety problems and allow noise interference. Users and technicians also often find it difficult to determine the purpose of components in disorganised units.
Many older and customised control panels fail to meet National Electric Code requirements. As a result, they also fail to meet some of the National Fire codes. Obviously, older units with worn and/or damaged parts are fire hazards. Disorganised units can also fail to provide enough required space. Many units simply fail to provide appropriate printed markings, such as part labels and system diagrams.
In this case it is better to replace your control panel.
Badly located panels can also make servicing more costly, and if located in a damaging or corrosive environment, shorten the working life of the panel.
