Key takeaways
- ATS restores power automatically in seconds — best for critical/unmanned loads.
- Manual changeover is cheaper but needs someone on site.
- Match the choice to how critical your load is.
- We supply and connect both as part of your power setup.
When mains power fails, how quickly your generator takes over depends entirely on your transfer arrangement. The choice between an automatic transfer switch (ATS) and a manual changeover comes down to how critical your load is and whether someone is on site.
Automatic transfer switch (ATS)
- Detects mains failure and starts/transfers automatically in seconds.
- Essential for unmanned sites and critical loads.
- Transfers back to mains and shuts the set down on restoration.
- Removes human delay and error from the changeover.
Manual changeover
- Lower cost, simple and robust.
- Requires a person on site to switch over.
- Fine for non-critical loads where a short delay is acceptable.
How to choose
Critical or unmanned operations — data rooms, clinics, telecoms, cold storage, security — almost always justify an ATS. For occasional, attended backup on non-critical loads, a manual changeover can be the practical, cost-effective choice.
Think about who is on site at 2 AM. If no one is, an ATS is usually worth it — power restores itself without a call-out.
We supply and connect both
Whether you need an ATS panel, a manual changeover or a synchronised system with multiple generators, we can supply, install and commission it as part of your temporary or permanent power setup.
Frequently asked questions
If the load is critical or the site is unmanned, yes — an ATS restores power in seconds without anyone present. For attended, non-critical use, a manual changeover may be enough.
