Why Installing a Transfer Switch Is Essential for Your Home Generator
When the power goes out unexpectedly, your home generator is your lifeline. It keeps the lights on, the fridge running, and essential systems like heating and security operational. But to unlock the full potential of your generator and ensure a seamless transition during an outage, there’s one piece of equipment you can’t overlook: the transfer switch.
At GFE Power Products, we supply high-performance, new diesel generators for homes and businesses across the UK and internationally. And when advising our customers, we always highlight the importance of installing a transfer switch as part of their standby power setup. In this article, we’ll explain what a transfer switch is, why it matters, and how it can transform your generator system into a safe, reliable power source.
What Is a Transfer Switch?
A transfer switch is an electrical device that automatically or manually switches your home’s power source from the grid to your generator in the event of an outage. It is installed between your generator and your home’s main electrical panel.
There are two main types:
- Manual Transfer Switch: Requires you to switch the power source manually when the mains supply fails.
- Automatic Transfer Switch (ATS): Detects a power outage instantly and activates the generator without you having to lift a finger.
For residential installations, an automatic transfer switch is often the preferred choice, especially when continuous power is critical or you’re away from home.
Why You Shouldn’t Run a Home Generator Without One
Some homeowners are tempted to skip the transfer switch and plug appliances directly into a portable generator. This may work for temporary setups, but for a whole-house generator, it’s not just impractical, it’s unsafe and often illegal.
Here’s why installing a transfer switch is essential:
Safety First
Without a transfer switch, you risk backfeeding, where electricity flows from your generator into the utility lines. This can endanger utility workers and damage electrical infrastructure. A properly installed transfer switch isolates your home’s circuits, eliminating this risk.
Seamless Power During Outages
With an automatic transfer switch, the transition between mains power and generator power happens instantly. No fumbling in the dark, no plugging in extension cords. Just uninterrupted comfort and security.

Power Your Whole Home, Not Just a Few Devices
Plugging a few appliances into a portable generator only gets you so far. With a transfer switch, your generator can power multiple circuits or your entire home, including:
- Heating and cooling systems
- Refrigeration
- Security alarms
- Wi-Fi routers
- Medical equipment
- Electric garage doors

Transfer Switches and Compliance
In the UK, installing a transfer switch must comply with BS 7671 wiring regulations. It must be fitted by a qualified electrician, and in many cases, the work must be notified under Part P of the Building Regulations.
At GFE Power Products, our global dealer network have certified engineers who can install your new transfer switch. However if you’re unsure what your system needs, get in touch with our team and we’ll help guide your decision.
Choosing the Right Transfer Switch for Your Generator
Selecting the right transfer switch depends on:
- Generator size (kVA rating)
- Single-phase or three-phase configuration
- Automatic vs. manual operation
- Critical load requirements
Most of our customers with residential or light commercial needs opt for automatic transfer switches matched to their diesel generator’s output.
We recommend reviewing your electrical usage and prioritising circuits that must remain powered during an outage. If you’re installing one of our GFE Powered diesel generators, we can supply compatible transfer switch options tailored to your model.
Peace of Mind During Every Power Cut
Think of the transfer switch as your system’s smart controller. It detects utility power failure, switches your home to generator power, and switches it back again when power is restored, all with no action from you.
This means you:
- Avoid power surges and manual switchover hassles
- Prevent food spoilage or frozen pipe damage
- Keep your alarms, lights, and boiler online even when you’re away
In short, a transfer switch transforms your generator into a true backup power solution, not just a backup appliance.
Installing a generator without a transfer switch is like installing a car engine without a key. It may technically function, but you’ll never unlock its full value or convenience. With a transfer switch, your home generator becomes a true asset, protecting your family, safeguarding your comfort, and giving you peace of mind.
