I will never forget this joke told to me by an old shop master.
What do you call an electrician that does a carpenters job?
A bad carpenter.
What do you call a carpenter that does an electricians job?
Dead.
When it comes to electricity I think any rule discouraging calling a professional would be irresponsible and dangerous. DIY advice can absolutely include info on how to hire and ensure you get a good honest deal from a contractor IMO.
Fwiw I’d agree, especially if it ends up being a matter of just having a professional look at and test it to confirm it’s something you could handle yourself.
