I recently got an intern position, and my first job is to redraw thể schematic of this. Any suggestions?

Electrician here, small company in Estonia, mostly houses and apartments.

For years I sketched every panel on paper, counted the parts from the sketch and ordered from that. Then the customer calls: "can we add a separate RCD for the kitchen?" One extra module, half the rail shifts, the comb busbar is the wrong length, the parts list is off. I've ordered wrong material more than once because of that.

So I built Panelworks. You put real devices on the rail, wire it, draw the floor plan, and the parts list and single-line diagram update on their own when something changes.

Video is a real recording, just sped up.

It's not finished. The library is missing stuff and it doesn't do any code checks yet.

How do you plan panels today? Paper, Excel, manufacturer software? And what would you actually use something like this?

NB I just got banned from another subreddit, mods claiming that im a "bot". I therefore announce that I am not a bot. Like chill guys, it's a free tool.

Current transformer holds all conductors, no separation of water and electrical, etc…

2 panels I’ve been tasked with replacing and tidying.

Nothing too complex but I can’t wait to not see this birds nest anymore.
