Transfer Switch On Diesel Generator

Transfer Switch On Diesel Generator

Equipping your home or company with a diesel generator is a great way to ensure necessary backup power when you need it most. And here, lets talk about the role of the diesel generator transfer switch.

 

One of the most important accessories of a diesel generator is the transfer switch. This little add-on makes the backup power process seamless and helps ensure overall safety. Here’s a brief overview of the role transfer switches play and the importance of having them.

 

 

What does the transfer switch do?

 

In simple terms, a transfer switch is a permanent switch attached to your power box that changes the power load between two power supplies.

 

For permanent backup power, this happens automatically when the first power source is unavailable. This is ideal as it keeps the energy flowing seamlessly with minimal delay.

 

In the case of diesel generators for corporate electrical use, the diesel generator plugs into a transfer switch located on the circuit board. When the diesel generator starts, the transfer switch switches the load from grid power to the generator.

 

Which generators need a transfer switch?

 

Homes and companies almost always need a backup diesel generator. Since they’re always waiting for outage time, it’s important to have this extra piece of equipment to keep power flowing without downtime.

 

However, portable diesel generators do not strictly need a transfer switch, and the biggest benefit of using a transfer switch in a stationary scenario is that you can power the unit through the breaker panel without having to use an extension cord. This includes hard-wired equipment such as various appliances, computers, air conditioners, office appliances, construction tools, etc. All you have to do is plug the portable diesel generator into the power cord and you’re ready to start delivering steady power to these devices!

Do you need a transfer switch?

 

If a diesel generator exceeds 5,000 watts, a transfer switch is always required for safety reasons and easy of use. This is important to keep in mind as the generated power levels require the use of regulators to help prevent surges and feed back to the grid.

 

The risk of not using a transfer switch?

 

Not using a transfer switch has many risks beyond simple convenience. In some cases, not using a transfer switch can jeopardize the safety of employees or even workers employed by the power company.

 

The main case where this becomes a problem is known as a back-feed grid. This means that when you are using the generator without a proper transfer switch and the mains is on, there are two currents supplying your company. Such a surge could cause problems on production lines that could put grid workers at risk. It can also cause a fire in your home or company. That’s why it’s so important to have a transfer switch.

 

Now, let’s be clear, we’re talking specifically about backup diesel generators attached to your worksite or office panels. If you are using a portable diesel generator and just plug a few pieces of equipment or other construction workers willing to plug directly into the generator, this is not considered a problem.

The type of transfer switch?

 

There are two different types of transfer switches – automatic and manual. As the name suggests, automatic transfer switches seamlessly route power from mains to backup when needed. It’s always there, ready to switch power to a generator when needed.

 

Manual switches require a person to flip a small lever and turn them on, hence the name. Portable diesel generator often require manual switches because they are not always plugged in. Permanently installed backup diesel generators may require manual or automatic, but automatic is usually the most convenient option. After all, who wants to travel long distances to the engine room to turn on generators to restore power when the grid goes out?

 

For most companies, the need to automatically transfer to backup power during a power outage is critical.
