UL 508a is a control panel standard that must be met by industrial equipment. The control panel design goes a long way in determining the safety and functionality of the machinery. In the construction of control panels, there are many factors to consider. Firstly, the panels must meet safety standards and regulations stipulated by the UL and National Electrical Code. Other provisions are NFPA and CSA. Apart from meeting the regulation standards, the panels must also be well constructed for the safety of workers.

UL 700-4P is the flexible standard for hazardous location, industrial control panel and instrumentation protection. It can be applied when the ICP is located in a hazardous location such as an underground vault, in a hazardous chemicals area, or in the interior of a high-temperature kiln.
UL 508-2 is a standard that protects small (<50 kVA) substations and distribution transformers from accidental live voltage transients. It provides protection for supporting electrical equipment and for power line equipment. It is a big component of the requirement that all distribution equipment be safely enclosed to prevent electric shock.
This standard states that equipment should be designed to accept and reject remote power connections through the normal handhole and emergency handhole as well as at a ground fault interrupting outlets located at the normal and emergency handholes. It also requires that the equipment be designed to perform at continuously 90%, but not greater than 110%, of normal power output at the normal handhole for not less than 15 minutes and not less than 90 minutes in the event of a power failure.
