Hello everyone,
Our house is slowly but surely taking shape, and of course, the double garage must not be missing. Since we built the garage ourselves, the electrical work is also our responsibility. I’m not going to mess around with it, but I’d like to know in advance what makes sense.
Chasing the walls for cables and laying them is manageable.
For the garage, I am currently considering two approaches:
Two separate electrical circuits in the garage:
One circuit to power the six outlets distributed throughout the garage
A second circuit for two lighting circuits; one controlled by a motion sensor that automatically turns the garage lights on and off depending on the brightness (access to the house through the garage is possible), and a light switch that controls a constant light with multiple fluorescent tubes for when working on projects in the garage.
Does this have to be done with two separate circuits, or is a single circuit distributed via a junction box sufficient here?
Should a separate fuse box (distribution board) be installed in the garage, or is it sufficient to protect everything from the main fuse box in the house?
Thanks and best regards
Georg

- with 5x16mm² (5x0.0063 in²) cables to the small distribution box in the garage.
- 1x 32A outlet
- 2x 16A outlets
- one circuit breaker for the garage doors
- one circuit breaker for lighting
- one circuit breaker for outdoor socket(s)
- one circuit breaker for general sockets
- 3 circuit breakers for workbench power
- ...
- don’t forget the network cables

You definitely forgot the RCDs. No matter what, the garage and outdoor sockets should always be protected by separate RCD(s).

Caspar202020 Sep 2017 12:12Had to be done quickly. Still, 5x16 meters (16x52 feet) is somewhat oversized for a garage; but on the other hand, no RCDs are specified...

...It depends on how much space you have in the garage and what you want to use it for. I have a simple garage where my car is parked. I basically only need electricity sometimes for a battery charger, vacuum cleaner, a light at night, and power for the garage door opener. I have never used my three-phase power supply.Hello everyone,
Since this fits the topic quite well, I’m bringing up this old thread again.
We are currently building a semi-detached house through a developer. Tomorrow is the final selection of fittings. Our house will have a carport including a bike storage room. By default, no electricity is installed there. However, for 500€ we can have power supply and a separate distribution board installed in the carport. A standard cable run is included.
My question is: what should I pay attention to tomorrow to ensure that this power connection/distribution board will be sufficient later on to install a 22 kW electric vehicle charging station if we decide to go electric? Apart from power and lighting, we won’t need anything else in the future.
Is it really that simple to say? I suppose the most important thing is that the underground cables have a large enough diameter?
Thank you for your help
