ᐅ Self-Work – Electrical Cable Installation Through Multi-Utility Entry Sleeve

Hello everyone,

In our new build (currently at the shell construction stage), we have a multi-utility house entry (I will refer to it as "MHE" from now on) located in the utility room.

I am allowed, in coordination with our electrician, to run a power cable from inside the house to our future garden shed. The electrician will handle connecting it to a dedicated 16A circuit breaker.

The electrician suggested that I simply drill through the wall and seal it (possibly with bitumen). I would rather avoid this, as I want to use the MHE.

My plan is to run the cable from the distribution panel to the MHE (approximately 2m (6.5 ft)). I would like to lay the power cable on the floor so that it can later be embedded in the screed.

My question:
Right before the MHE, the cable should come out of the screed, correct? Or do you have a better idea (for example, drilling through the body of the MHE)? My wife would prefer not to have this cable visible...

I have attached a picture where I have tried to illustrate this.

Is there anything else I should consider? There are blue pipes in front of the MHE (I believe they are for heating(?)). I would have to cross them. Am I allowed to do that, or should I use a conduit instead?

I hope I posted this question in the right section.

Thanks and best regards,
Fabian

You should take a closer look at the rest of your multiservice installation. That way, you will understand the purpose and function of the remaining parts missing in the photo.

If you don't have a gas connection, you can use the empty conduit for this purpose.

How do you come to the conclusion that there is no gas connection?

Thank you for your reply @Bau-Schmidt. Your answer probably means that drilling into the body of the MHE is pointless, since the pipes are supposed to be routed from above through the seals. So, there is no other option than to let the cable come out shortly before the MHE through the screed and then lead it “S-shaped” through the seal to the outside, correct?

That would be considered poor workmanship in my case. A cable conduit or empty duct should be installed along the wall and then connected to the multi-utility entry point.
