You've got romex in conduit?

I'm not an electrician, just a DIY enthusiast (and the parent commenter) - but in North American construction, romex in conduit is basically unheard of in residential builds - it's stapled to the framing during construction, so once you cut wire short, you've immediately put yourself in a pickle.

We use rigid 16 mm pvc conduit (bend with heat) with 2.5mm2 wires in brown(+) blue(-) yellow/green stripe(gnd) and 1.5mm2 black for switched wires.

Ideally you bend the pipe as little as possible and make the corners as smooth or as blunt as possible. If done properly you can later add extra wires. If not done properly you only get the illusion you can.

With romex you have to anticipate future changes.

Here in the states, putting Romex in conduit is considered a code violation. You're supposed to use THHN wire in a conduit.

I wish professional electricians use pigtails and wago lever nuts instead of wire nuts. Working an old house, I've had to cut way too many wires almost too short just to add another neutral or ground.

I don’t think they implied Romex? Conduit is mandatory in multi-family construction here in San Francisco, but they just use armored cable, not romex in conduit.
