EV Charger Installation Process Pt 1: Cable Routes

There is plenty of information online helping EV buyers choose which EV home charger will best suit their needs. (We have a comprehensive post on the topic here!) However, there is not much information on how these installations are carried out. If you want to understand the EV charger installation requirements and how such an installation will affect your property, then keep reading! This is the first in a comprehensive series of posts on the EV charger installation process. This post will explain how the cables can be routed from your fuse board or electricity meter to your charge point.

Useful EV Cable Tips

Before going through the different methods of routing the EV charging cables, there are a few points to consider. You might think of these cables as small and discreet, like the lighting cables you will find in your house. However, because these cables carry so much current, they are thicker than you would expect. They are about the size of a hose pipe. Keep this in mind when considering discreet cable routes.

The cabling will almost always need to run directly from a suitable fuse board or electricity meter to the charge point. It can’t be spurred off an existing circuit. In most properties, the electricity meter and fuse board are located very close together (either in the same cupboard or on opposite sides of the same wall). However, if the fuse board and meter are separate, we look for the neatest option. Each property is different, so we will discuss the specifics with you before we begin the job!

Another tip to keep in mind is that the cables need to be properly attached to something to be installed. If your EV charger is away from the wall of the house or garage, the cables might need to go underground. This is often the case if a new supply is required to a detached garage. If the cable needs to run underground, then a suitable trench is required. This trench must be 40cm deep when crossing soft or unmade ground. Don’t be worried about this, as our team of experts will be able to help you find the best route for your cables.

The following methods of cable installation are only meant as a guide. Each case will be different and require a unique approach. Our team will work with you to find which method best suits you, to give you the most discreet and unobtrusive cable routing possible.

Cable Routing Methods

If your fuse board or electricity meter is outside the property or against an external wall, the routing process is simple. The cable can be drilled through the wall and then run discreetly along the outside of the house to your desired charger position. The cable can be run at ankle height or up towards the eaves. Nothing complicated about it!

If your fuse board and meter are in the middle of your property, away from an external wall, there are several possible options. The first option is to run the cables under the floor, which is possible if your floorboards can be lifted. This can often be done relatively quickly and should not cause you much disruption. However, this does depend on what we find under the boards – some properties have a large void while others are very shallow, which makes routing the cables tricky.

If under the floorboards isn’t an option, then the cable can sometimes be run upstairs through the first floor. If your floor is solid or has underfloor heating, this will likely be the case. This takes slightly longer and requires more disruption, but we will get the job done!

Finally, the cables can be run in surface-mounted trunking to neatly conceal the cables. The cables may need to be placed in prescribed zones when running through the walls. This isn’t a problem, but it is useful to know that running the cables in your desired direction might not always be possible. These decisions will be made on a case-by-case basis, and we will help you find the neatest and least obtrusive cable route possible

By now you should have a good idea of which cable routing methods will work best for your property. If you want to learn more about EV charger installation requirements or the installation process, then don’t hesitate to get in touch today.
