IEEE-oriented protective equipotential bond, connecting exposed metal parts together for safety.

## In plain English

### What does ANSI/IEEE protective equipotential bonding mean?

The protective equipotential bond connects exposed and extraneous conductive parts so that dangerous touch voltages cannot develop between them during a fault. The publisher's IEEE miscellaneous preview lists a protective equipotential bond form, which is the US-practice counterpart of the existing IEC page.

### A simple example

This illustration is an independent explanation and not the IEEE graphic. The bond symbol does not state conductor size or the parts bonded; those belong in bonding schedules. In US terminology this aligns with equipment bonding, which is distinct from the main bonding jumper at the service.

### What the drawings help you do

Identify the parts bonded at each symbol. Distinguish equipment bonding from the service bonding jumper. A protective bond is for safety; a functional bond is for equipment operation or noise control.

### This particular reference

IEEE-oriented protective equipotential bond, connecting exposed metal parts together for safety. A protective bond is for safety; a functional bond is for equipment operation or noise control.

### Terms

- Rating: A value stating the conditions for which equipment is specified.
- Schematic: A drawing showing function and connections rather than physical appearance.

## How to read it

- Identify the parts bonded at each symbol.
- Distinguish equipment bonding from the service bonding jumper.

## Information to show or reference

- Schedule bonding conductor sizes.
- Label bonded parts.
- Keep protective and functional bonds distinct.

## Important distinction

A protective bond is for safety; a functional bond is for equipment operation or noise control.
