What must be done with bare conductors before splicing?

Before splicing bare conductors, they must be bonded and grounded to ensure safety and prevent electrical hazards. Bonding refers to connecting different pieces of conductive material together to ensure they are at the same electrical potential, which helps prevent shock hazards and allows for proper operation of the electrical system. Grounding provides a safe path for electric current in the event of a fault, thereby protecting people and equipment.

Grounding and bonding are critical in electrical installations as they mitigate the risks associated with electrical faults. If bare conductors are not properly bonded and grounded before splicing, it can lead to dangerous situations, including electrical shock, equipment damage, or fire risks. Therefore, ensuring that conductors are correctly bonded and grounded is an essential step in the splicing process.
