ᐅ Connecting the Electrical Distribution Board in a Construction Site Container

Hello from NRW, my name is Michael and I have the following question for the electricians among you: what is the best way to connect the fuse box shown in the attachment to the distribution board, or vice versa? My friend is a trained mechatronics technician and has all possible personal protective equipment, such as complete tools and gloves rated up to 15,000 volts, as well as a lot of experience connecting car Hi-Fi systems. The fuse box is located in a locked area inside a container, and we are planning to set up a garden shed there. The cable from the distribution board is already inside the container, and everything is, of course, protected by circuit breakers. What is most important to us is which fuse should be connected from above and which from below to get 230 V (no need for three-phase power), and an electrician is not available for less than $250 (that is about as much as we plan to spend on the whole shed). Is there an electrician here who can possibly advise which fuse to connect from which direction and preferably in which order? We are fully aware of all the dangers involved with high voltage and only use gloves certified by the electrical association. Therefore, we are only asking for a completely non-binding brief guide, and connection will only be made when there is no power (we have a suitable multimeter and everything protected). We only work on the fuse box when the power is off and only with appropriate tools and gloves, always checking three times with the multimeter. We are very grateful for any help and would be happy to thank you with a box of beer and anything else imaginable (even if the helper is not from NRW). Many thanks in advance and sunny greetings from the Ruhr area, Michael

PS: Of course, we did not connect the fuse box ourselves and do not know who made the previous faulty installation. We are both sure that it was not a professional, and we would never put it into operation that way because we are fully aware of the dangers.

You should not connect anything there! This should definitely be done by a qualified electrician, who should also properly service the electrical panel at the same time.

What a mess! Hopefully, no electrician connects anything like that. Using a green/yellow wire as a live conductor is criminal and actually intentional rather than just negligent. The whole setup is life-threatening.

A truly well-intentioned piece of advice: I personally do almost everything myself and I am quite confident in my abilities. Generally, wiring a circuit breaker panel is not rocket science. And yes, you have the equipment. But what has been done so far is absolutely shoddy work! It is extremely dangerous. If you don’t even know how to connect and operate a circuit breaker, then this is simply a job for a licensed electrician.

By the way: Car hi-fi systems running on 12V are not even remotely a qualification for electrical work. That made me smile.

That made me laugh too.

And after seeing the pictures of the dangerous exposed wiring, it was clear: call in an electrician.

You are right, do you maybe know what the approximate cost would be for 60 minutes of work? Rough estimates are fine. Thanks a lot and best regards, Michael

For small jobs like this, I would always post on a platform like MyHammer and let the cheapest quote win.

My guess is that this will be more expensive since new materials will also be required.
An electrician will probably want to replace at least the "panel," as they won’t be able to fix it properly otherwise.
To my knowledge, an electrician is always responsible for the "whole system," even if they only make minor changes.
At least, that’s how I understood the electricians who refused to renovate the electrical system in my older house.

This unfortunately often leads to extensive inspections (and then changes) in such situations.

The cables look very thin; depending on the length of the wiring, those might also need to be replaced.
Buried cable? UV-resistant cable above ground inside protective conduit?
The poor workmanship will just cause problems elsewhere... No matter how cheap the house is or was, have it done properly and safely!!!
A human life is very difficult to weigh against money!

Hello

I also think an electrician wouldn't take this on.
Either the panel is replaced. You already have the DIN rail, fuses, and RCD.
Or you undo everything for now and rewire it. You have some knowledge, as you said. But continuing with this poor workmanship won't lead anywhere.
