What Is the Size of the ATS Your Generator Needs?

Most people searching for backup power start with the generator. The switch comes later, and that is where many projects stall. An undersized switch overheats, and a mismatched one will not suit your supply at all. If you plan to buy anAutomatic Transfer Switch in the UK, the amp rating is your first decision. The switch must carry the full load of your site without strain.

What does an automatic transfer switch do?

An automatic transfer switch (ATS) watches your mains supply. You do not need to touch anything.

Our ATS panels also provide a safe link between the two supplies. That protects your equipment, and it protects engineers working on the network.

A 100A switch would then be the sensible starting point. We offer panels by amp rating, so you can match the figure closely.

Single-phase or three-phase?

We supply and install ATS panels for both. Your electricity supply decides which one you need, so check your meter or your distribution board first.

Our home and small business packages pair an 8 to 22kW single-phase generator with a 63 to 100A ATS. For commercial and industrial sites, we offer three-phase generator sets with a rated ATS. Deep Sea monitoring and maintenance bypass options are available on those systems.

Buying the generator and the switch together

Many customers ask us about used generators for sale in the UK. A used set can lower your upfront cost, and the same sizing rules apply. You still match the switch to the generator and to your site.

What makes our panels different?

FAQs

What amp rating do I need?

Base it on your maximum load and your generator output. For home and small business use, our packages pair 63 to 100A switches with single-phase generators.

How fast does an ATS switch over?

Our automatic transfer switches move your load to the backup supply within seconds of detecting a mains failure.

Does Blades Power Generation sell the ATS on its own?

Yes. If you already own a generator, you can order the panel alone by amp rating.
