What is required before using temporary electrical power sources?

Before utilizing temporary electrical power sources, it is essential that they are inspected, certified safe, and tagged. This requirement ensures that the equipment meets the necessary safety standards to prevent accidents or hazards associated with improper use. Inspections help identify any potential issues, such as faulty wiring or inadequate grounding, which could lead to electrical shock, equipment failure, or fires. Certification signifies that the temporary power source functions correctly and is safe for operation, while tagging indicates that it has passed inspection and is ready to be used.

While it's important for qualified personnel to operate equipment, mere qualification does not ensure that the temporary source is safe. Similarly, connecting temporary power sources to a permanent supply is not typically required, as temporary systems often exist independently to provide short-term power. Lastly, although it is advisable to have electricians involved for installation, not all temporary setups necessitate a licensed electrician, especially in non-complex applications. Thus, the focus on inspection, certification, and tagging highlights the emphasis on safety as the primary concern.
