Which of the following is not a basic rule of electrical safety?

The principle of working by yourself contradicts fundamental safety practices in electrical work. Engaging in electrical tasks alone increases the risk of accidents and makes it difficult to receive immediate assistance in case of an emergency. To ensure safety, it is advised to work with a qualified partner who can provide support, assist in emergencies, and enhance overall safety awareness on the job. By having a partner, both participants can communicate effectively and help monitor each other's safety, greatly reducing the chance of injury.

The other options are integral components of electrical safety protocols. Wearing personal protective equipment is essential to protect against electrical shocks and other hazards. Working in dry areas minimizes the risk of electrical shock, as moisture can conduct electricity and increase danger. Therefore, the option stating to always work by yourself does not align with established safety guidelines in electrical work.
