The cable seller guy recommended using breaker as a connection as well. Or if I follow the connecting cable route, connecting through cos (as attached picture) is highly recommended....I would recommend NOT soldering these joints. You will have something like the pictured fixture in VN to make a good mechanical connection, if not affixing into panels and breakers. Be safe!
2 electricians I know think directly connecting the cables (using cos) and using one CB might be best choice (but they don't have experience in audio (not an audio user), actually one of them do run dedicated line for a few studios, but never encounter this situation before).
I just ordered 15m of the same Gigawatt cable. The existing 15m provided by national electricity company will be used for general electric line. Decision now is only whether to use 1 CB with interupted cable or 2 CB for this audio dedicated line.Hello Novacdjokotoet
1. If that 15 mt. cable from meter to panel on first floor is a separate line for audio then it’s better to replace it with the same cable that you use from panel to third floor -In this case GigaWatt LC-Y EVO 3X4-. Then getting rid of the second CB on the first floor and connecting two cables with appropriate connector or soldering is the best option IMHO. This way you can have a cable with one interruption and one CB.
2. If that 15 mt. cable from meter to panel is a common line both for audio and anything else in the house then use it as it is. Alternatively you can replace CB with Gigawatt’s.

More importantly please check your country’s electrical code before doing any of the above mentioned alterations.
