Spot the minor error here.

Sounds/looks like it might have started off in Italian and lost a little in translation (i.e. some the technical volcabulary isn't quite what we're used to), but the only actual error I spotted was the narrator mis-pronouncing Icc as "ell see see" rather than "eye see see" - which feels very minor indeed.

I wonder what else I over looked?

Otherwise it seemed quite informative - I wasn't aware there existed type 1 SPDs that had additional electronic "enhancements" built in speed up the arc creation process or indeed MCB style arc splitters.

i noticed the double width SPD had two "L" terminals at the top, and a combined "N" and "PE" terminal at the bottom.

and no indicator on the front

I might be wrong, but I presumed that each module was "single pole" - so the double L terminals at the top were handy when looping through the line conductor and then the bottom terminal could be connected to either N or PE depending on the arrangement needed (e.g. CT1 or CT2).

It seem quite common for type 1 SPDs not to have an indicator - perhaps the spark gap types aren't as liable to failing as the metal oxide varistor usually found in type 2s.

Yep, that was wot I was referring to. Current as "L". And the unusual use of the word "solicited".
