ISL are experts in switchboard manufacturing.

Our knowledge is sought after by organisations who have installed switchboards that sadly fail to meet the minimum industry standard or are constructed to the lowest standard possible. Unfortunately, this exposes the site and production to breakdowns, malfunction or in a worst-case situation fire. Many electricians lack the specialised experience and knowledge assessing an industrial electrical switchboard accurately. With ISL on board you can rely on us to get it right.

Flexible Design

A common mistake by switchboard designers is failing to consider fully the client’s growing needs in pursuit of offering the cheapest price to attain the contract. Unfortunately, these switchboards fail to meet or soon fall short of the clients' requirements.

Expensive modifications (or total replacement) are often necessary to satisfy production growth, site upgrade or expansion.

ISL believe in taking a more considered approach - we build with the future in mind.

From the start, ISL design and construct switchboards around your specific requirements – both current and in the not-so-distant future – ensuring a longer life is part of the intrinsic design and planning. A long-term view is critical to ensuring capital expenditure is maximised and not made redundant if a site’s power requirements change.


Our ethos is about thinking smarter, adding value over a long term.

The cost of terminating switchboards mostly lies with the electrician / labour. This is often a time consuming, expensive process if a poor and inflexible design has been installed by the switchboard builder. Quality considered design from ISL provides a more enduring and elegant solution which will save time for the electrician and ensuring a better result for the client to achieve their goals.
