Most electricians don’t do this type of work, I’d say. For a grid operator, sure. For the standard guy coming to your house to do some wiring? No way.

After a major blackout, I think it's fairly common for electricians to have a lot of work on; distribution boxes etc often don't take it well.

Is this something common in Europe? We’ve had our fair share of blackouts in the US, some lasting days, and I’ve never ever heard of someone’s breaker panel (I assume that’s what you mean by distribution box) needing any service as a result of the blackout.

I've had one power cut in the last decade (urban area, wiring generally underground), but I know people in rural areas who have power cuts a lot due to storms, and sometimes there are problems coming back up. Think it's mostly old-fashioned 'fuse boxes' with actual literal fuses in them that have problems (you don't strictly need an electrician to sort that, but some people are nervous of the giant fuses and I'm not sure I blame them...)

I don't think it's a particularly _common_ issue, but it definitely happens to some extent.
