Romex is one or more insulated conductors with an overall insulating jacket.Quick question chaps
What is Romex wiring it's a term I have not come across in the U.K.. Is it similar to what we call T&E (Twin and Earth) which consists of two Insulated conductors and an uninsulated earth (ECC) conductor in a secondary insulated sheath. it is the standard for domestic fixed wiring here.

Romex I think is a brand name, but that is what folks call residential wiring these days.
In home use, the wood studs are drilled, and the Romex routed through the studs horizontally, or stapled to the studs vertically.
The smaller gauge Romex such as #12 and #10 is a solid wire, which actually works quite well, but is a bit more cumbersome to terminate in a junction box.
A solid wire makes for a very good screwed connection if you get the screw tight.
Stranded wire has to be carefully terminated so that a single stray strand does not protrude out somehow and conduct too much current, which can melt the single strand.
In industrial/municipal work, solid wire is not allowed, due to vibration and other issues.

You can get Romex with one or more energized conductors, often called 2-wire, 3-wire, etc.
You have to be careful with Romex when installing the sheet rock on top of the studs that you don't use long screws, and don't drive a screw or nail into the Romex. They do make metal shields that you can place on the studs under the sheetrock to prevent nailing/screwing into Romex circuits, and I have used these devices.
