Answer:
24 V, 50 V, 150 V and 250 V
Step-by-step explanation:
Electrical bonding consists of deliberately connecting exposed metal elements that are not intended to conduct electricity in a room or a structure to protect people from electric shocks. If there is any failure in the electrical insulation, all these metal elements will share the same electrical potential, preventing accidents from happening. In strengthened methods of electrical bonding, the voltage to the ground cannot exceed the figures mentioned above.
