Do You Need a Manual Changeover Switch With Your Generator

When there is a power cut, a large number of people go to a generator. The next thing to consider is how to safely connect the generator to the building. At Blades Power Generation, we design and provide the switches which solve this problem, and a manual changeover switch is usually the best starting point. 

Why Backfeeding Is the Risk to Avoid

Backfeeding occurs when the power produced by the generator is fed back into the electrical supply network. Repairmen working on damaged lines could then come into contact with live cables. In order to prevent this, an interlocked switch shuts off that route, so that the only thing the generator supplies is your building.

That is why we recommend switching to proper connections instead of using improvised ones.

The Benefits of a Manual Changeover Switch

A well-built changeover panel gives you several practical advantages:

·        When switching over, you make the transition from utility power to generator power in a clear and deliberate manner.

·        There is an interlock protection feature which prevents the main supply and the generator supply from being connected simultaneously.

·        The design is cost-effective for sites that have a planned maintenance schedule.

A manual changeover switch is suitable in the case where someone is available on site to operate it and when a brief delay in power supply can be tolerated; a workshop having staff on site is an example of this. An automatic transfer switch, on the other hand, picks up a failure of the main power supply and switches your load over to the generator within a few seconds without any need for manual action. That option suits sites where nobody may be there when the power drops.

We supply both types, and we pair either one with generators from our range, including new generators for sale in the UK.

Quick Answers

What size switch do I need?

The right rating depends on your generator output and your site load. Our engineers can help you specify it.

Can I add an automatic switch later?

You can choose an automatic transfer switch at the start or review your options as your needs change. We can talk you through both routes.

If you search for new generators for sale in the UK, look at the switch as closely as the engine.
