I can’t really imagine that you can still get 10m (33 feet) of 5x 6mm² for 30-60€ (copper prices are through the roof)

If you can’t find it in the store, classified ads are your friend 😉

Hello everyone,

interesting topic – I’ll jump right in, even though it's a bit of a different context (didn’t want to start a separate thread). We are currently planning our electrical installations, and the topic of e-mobility came up as well. Initially, our plan was to have a high-voltage cable installed directly into the garage, as described here by HTR. However, I came across information online suggesting that with the increasing number of electric vehicles in use, building insurance costs might rise due to a supposedly higher fire risk. Are there any people here who can provide deeper insights on this? Is such a scenario realistic?

Otherwise, I’m thinking of installing the wallbox outdoors, some distance away from the house to be on the safe side (which would also have some advantages in terms of cable routing). What about the durability of a wallbox outdoors?

Thanks for your input

Best regards Roman

No, in my opinion that’s nonsense. I would definitely plan to install it in the garage. You still have the option to just install a standard 16A socket, like people have done for years. There are plenty of wallboxes you can simply plug in (Juice Booster, e-go) without hardwiring them. Then the insurance would not be an issue anyway, since you only need to report permanently installed systems 🙂.

Why build a garage if you plan to charge the car outside?

When planning the wall box, don’t forget to connect it to the network. Depending on the wall box, this can be via Wi-Fi or LAN.

Or via Modbus RTU/RS485. So it’s best to also provide cables for that as well.

Why use LAN cables if they need Wi-Fi anyway? 😳 But I guess the cable is intended for the wall box, not the car. 😉

He probably means that the Tesla wall box supports Wi-Fi and does not require a LAN cable. You can of course operate the wall box without Wi-Fi, but then you have fewer options to network and control it.
