Operating and maintaining electrical networks requires strict compliance with safety rules. Switching operators must ensure not only their own safety but also the safety of others who may be accessing the network. Both distribution and transmission switching involve high risks, so following proper procedures is critical.

In this article, we’ll highlight key safety principles in switching operations and show how EverExceed's power solutions support reliable and secure operations.

1. Tagging, Locks, and Barriers

To prevent accidental energisation, operators must use clear visual indicators and secure lockout systems. Some commonly used tags include:

Danger – Do Not Operate Tag: Prevents switching until authorized.

Caution – Vicinity Work in Progress Tag: Warns of nearby work activity.

Danger – Restricted Use Tag: Ensures only qualified personnel operate equipment.

Warning – Out of Service Tag: Indicates equipment is disconnected and unavailable.

Alongside tags, Locks and LOTO (Lock-Out/Tag-Out) procedures form the foundation of safe switching practices, physically preventing unauthorized operations.

2. Common Switching Operations

Switching operators must perform certain standard procedures carefully and consistently:

Proving De-energised: Always verify that the circuit is de-energised before work begins.

Applying Earths: Grounding ensures that any residual or induced voltage is safely discharged.

Portable Earths: Provide a temporary but essential safety measure during maintenance.

3. How EverExceed Products Support Safe Operations

At EverExceed, we design critical power solutions that enhance both safety and reliability in electrical networks:
