Low-voltage bonding or just LV Bonding, has been gaining attention across the electricity industry — but not in a uniform way. While a small group of early adopters has moved quickly to implement LV bonding in day-to-day work, most networks are taking a more cautious, deliberate approach. They are exploring how LV bonding fits with existing work practices, trialling different equipment options, and comparing it with practical alternatives.
This growing interest is driven by real changes in how electricity flows through low-voltage networks. With more solar panels, home battery systems, and electric vehicle (EV) chargers in service, it has become far easier for an LV line to be energised even when teams believe it has been safely isolated.
The Electricity Engineers’ Association (EEA) recognised this shift in April 2024 by updating its Technical Guide: Portable Equipment for Work On or Near Conductors to include LV bonds for the first time. This new section gives networks a clearer direction for managing LV energisation risks as they decide how and when to adopt LV bonding.
According to the EEA, LV bonds help protect workers from energisation caused by small-scale embedded generation (SSEG) such as rooftop solar, battery storage, and EV charging. A typical 10 kilowatt (kW) inverter can output around 48 amps, and portable generators can deliver more than 50 amps. These levels are high enough to create serious hazards for field crews if LV equipment becomes unexpectedly live.
The 2024 EEA guide includes a dedicated section on LV bonding and updates its terminology and requirements to reflect the changing risk landscape. This marks a significant shift, acknowledging LV bonding as recommended good practice across the country.
While the EEA has set out clear expectations, most networks are not rushing LV bonding into full-time field use. Instead, they are:
This careful approach reflects the real-world complexity of LV work. Networks want solutions that are not only compliant but practical, durable, and efficient for field use.
The updated EEA guidance provides detailed requirements for LV bonding equipment:
LV bonding:
LV bonding introduces new steps, new equipment, and new training needs. Because of this, networks are asking practical questions such as:
Rather than rejecting LV bonding, networks are working through these questions through trials, comparisons, and incremental adoption. Their approach is evidence-based rather than reactive.
LV bonding is rising in importance, but its adoption is unfolding at two different speeds. Some networks are already moving fast due to established live-line cultures and strong internal champions. Most, however, are taking a slower and more thoughtful approach, ensuring that LV bonding fits smoothly into their operations and complements — rather than disrupts — existing practices.
As trials progress and industry experience grows, LV bonding is likely to become more common. But it will happen through cautious, evidence-based decision-making rather than a sudden nationwide shift.
LV bonding isn’t just about following a guideline — it’s about building a safer, more predictable working environment in an LV landscape where “off” no longer reliably means “dead”.
