Surge protection - what is it, and do I need it?

Surge Protection Devices (SPDs) are pivotal, yet sometimes overlooked, elements in the safeguarding of electrical appliances against power surges. They are particularly important for electric vehicle (EV) chargers, given their susceptibility to the adverse effects of unforeseen electrical events.

That’s why a thorough understanding of SPDs and their benefits could not only save you a considerable sum in repair costs, but also prolong the service life of your EV charger.

The role of surge protection in EV charger installations

At the heart of protecting appliances from electrical power surges is the SPD. As part of the process of installing EV chargers, SPDs are generally integrated with the fuse box or consumer unit, serving as a safeguard against abrupt increases in electrical current.

EV chargers are notably vulnerable to lightning strikes, and SPDs play a crucial role in safeguarding both the vehicle and the home’s electrical system from such events. This protective measure is essential for ensuring the integrity and longevity of the electrical infrastructure within your home, and particularly within the EV charger itself.

SPDs are available in various types - Type 1, Type 2, and Type 3 - and each is designed for specific applications. Your installer will provide advice on which type is right for your installation.

Updates in regulatory standards

The introduction of the UK Wiring Regulations (18th Edition Amendment 2) re-emphasised the importance of surge protection in new electrical circuits, which encompasses new EV charger installations.

These regulations now require SPDs to be included to protect your electrical systems. So, while they’re not a mandatory aspect of our installation, we strongly recommend you default to including an SPD when purchasing one of our packages – for your safety, and for our market-leading low SPD cost – we charge just £99 for Surge Protection Devices to be added.

The risks of omitting surge protection

Neglecting to install an SPD can lead to considerable damage not just to EV chargers, but also to the vehicles and your home’s electrical set up.

The cost associated with installing an SPD is relatively low, particularly when compared to the potential costs of repairing or replacing equipment damaged by power surges, which might not be covered by your home insurance.

Choosing not to include an SPD may also have implications on the warranty of your EV charger, and it’s crucial to understand how this decision could affect the responsibilities of manufacturers in the event of surge-related damages.

At the extreme end of the scale, overvoltage incidents can lead to severe injuries or even loss of life.

With SPDs being relatively inexpensive, this makes the decision to include surge protection not just a wise precaution, but also an economically sound one.

The importance of expert installation

Dealing with electricity carries inherent risks, underscoring the necessity for professional installation. Opting for a reputable installation company is vital to ensure both your surge protector, and your EV charger’s, effectiveness and safety.

Surge protection should be seen as a vital consideration for EV chargers, in light of the potential risks and the regulatory framework.

Consider the safety and financial implications carefully, as most reliable advice leans heavily towards including surge protection during the installation of EV chargers, to ensure alignment with safety regulations, and protection against electrical issues.

But the effectiveness of these devices heavily relies on their proper installation. With safety and regulatory factors in mind, alongside the financial considerations, it’s reasonable to suggest that SPDs are critical in the context of EV charger installations, offering indispensable protection against power surges.

Think SPD safety

SPDs represent a smart investment, safeguarding your home, your assets and ensuring compliance with safety regulations.

So, as you purchase your EV charger, bear in mind the significant role surge protection plays in the safety and longevity of your electrical appliances before taking the SPD out of your cart.
