Hiring a Qualified Electrician

Connecting a generator to your home’s electrical system is not DIY. It can be dangerous and requires technical expertise. A licensed electrician must connect a generator to your home’s electrical system to ensure the process is done safely and correctly.

An electrician will assess your home’s electrical system to determine if it can accommodate the generator’s power output. They will also install a transfer switch to isolate your home’s electrical system from the primary grid to prevent back feeding, which can cause electrical shock, damage to your appliances, and life-threatening injuries to utility workers.

An electrician will also ensure that the generator’s wiring is up to code and that all safety protocols are followed during installation. They will also guide you on operating and maintaining the generator for optimal performance.

Hiring an electrician to connect a generator to your home may seem like an added expense, but it’s a small price for your safety and peace of mind. It’s crucial to have a licensed electrician do the job to ensure that everything is done correctly and safely. Remember, the safety of your home and your family is paramount. Generally, you don’t need planning permission for a generator if you’re using it for your household’s purposes. However, live in a listed building, a conservation area, or an area of outstanding natural beauty. You should check with your local council to see if you need planning permission.

What Size Generator Do I Need for a House?

The generator size you need depends on the wattage of the appliances and devices you want to power during an outage. Typically, a 5-10kW generator is sufficient to power essential appliances, such as the refrigerator, lights, and a few outlets. You may need a more powerful generator to power additional appliances, such as the air conditioner, water heater, or furnace. No, it would be best never to plug your generator directly into the mains. Doing so can cause back feeding, damage your appliances and be life-threatening for utility workers trying to restore power to your neighbourhood. Instead, you should connect your generator to a transfer switch, which isolates your home’s electrical system from the primary grid and allows you to power your home safely.

Connecting a generator to your house can be a lifesaver during power outages. However, following safety protocols and hiring a licensed electrician must ensure the generator is correctly installed. It is crucial to know the right size of the generator you need and how to connect it safely to your home’s electrical system. Remember, safety comes first! Whether it’s due to a power outage, maintenance work on the grid, or an unforeseen event, having a backup generator to provide power to your home can be invaluable. We’ve given a brief overview of what you need to know when connecting a generator to your house in the UK, from the initial purchasing decisions to the hiring of professionals.
