Hello
In 3 weeks, our carport will finally be delivered, after we had to wait a long time for the paving. I am currently planning the electrical installation for the carport.
Prepared by our electrician:
5x 2.5mm² cables, protected by a 30mA residual-current device (RCD) and 16A circuit breaker in the main electrical panel in the house
5x 4mm² cable, pre-installed without circuit breakers in the house for a 400-volt (400V) socket (electric vehicle)
Both cable ends were already routed to the correct locations in the shed next to the carport during the paving works.
I will carry out the installation myself. As a mechanical engineer with training in piping networks, I consider myself qualified for this type of work. Since the entire circuit also has its own circuit breaker, I can easily switch off the power (+ test with a multimeter...).
For the switch series, I have chosen Busch-Jaeger Ocean in blue, rated IP44 for covered outdoor areas. I will buy one 50-meter (164 feet) cable with 5x 2.5mm² conductors to connect everything. I wanted to use a 5-core cable so I can loop all five wires from the house throughout (even though only three are connected) and only need one cable to switch lamps, while the socket at the switch will have permanent power.
I plan to create three lighting circuits: one for the carport area, one for the shed, and one for the covered terrace (table lighting). Each circuit will also include at least 2-3 sockets. The carport lighting will have a two-way switch at two locations plus a motion sensor.
I want to run the cables inside Ø20mm (0.8 inch) electrical conduit (rigid conduit), fixing the conduits to the carport structure using quick clamps (OBO Bettermann). I’m not yet sure whether I can connect the cables directly from the conduit into the socket wiring using an M20 cable gland or something similar.
The 5x 4mm² cable I will only lay into a distribution box. If I ever need to connect it, I will leave that to an electrician.
Questions:
- Does 5x 2.5mm² make sense, or are 4 or even 3x 2.5mm² sufficient? Is 2.5mm² required for 16A?
- Is Ø20mm conduit enough, or would Ø25mm be better? I thought the 5-core cable would offer enough space (a 5x2.5mm² cable has a diameter of 13mm (0.5 inch)).
- Any suggestions for improvement?

Make sure that the pipe is approved for outdoor use, so it doesn’t crumble after three years due to UV exposure.I wanted to use the OBO Quick Pipe series for this. Unfortunately, I can't find any information online about their UV resistance. I can source the parts through the company.By the way, all the pipes should not run directly in the sun but always within the "interior area" of the carport. So, all the pipes are protected from direct UV radiation by the roof. According to the OBO product catalog, the quick pipes are not UV resistant. Strangely, they do not offer any UV-resistant plastic pipes either.
