What may result from inadequate bonding of an electrical system?

Inadequate bonding of an electrical system can create potential shock hazards. Bonding involves connecting various metal parts of an electrical system to ensure that they have the same electrical potential. This is crucial for safety, as it helps to prevent electric shock by ensuring that if there is a fault, the current has a safe path to ground. When bonding is insufficient, metal components may become energized, presenting a significant risk of electric shock to individuals who touch them.

The other options do not accurately describe the consequences of inadequate bonding. Increased efficiency, higher energy costs, and less wear on appliances are not direct results of bonding practices. In fact, inadequate bonding may lead to inefficient operation and potentially higher costs in other ways, but these do not relate specifically to the bonding issue that presents a clear danger to safety.
