For anyone interest I've attached a Room Component Wall and a product subassembly with electrical outlets.

Disclaimer - I created it in an imperial foundation library 25.0418 and tested it pretty good, shouldn't be any issues. If you do find any, I'd appreciate the feedback.

You can add up to four outlets per wall, with each outlet configurable as a single, double, triple or quadruple (1G, 2G, 3G or 4G) outlet. Each configuration can contain an outlet, switch, telephone and/or blank slot. You can place the outlets on the inside or outside of the wall and turn the outlets horizontally. Dimensions can be added from the left or the right of the wall. Plan and elevation draw tokens are included. These will not be included in hardware reports. This is a CUTX file, rename as required before dragging and dropping in your Room Component Products.

You can add up to four outlets per side (Top, Bottom, Left, Right, Back), with each outlet configurable as a single, double, triple or quadruple (1G, 2G, 3G or 4G) outlet. Each configuration can contain an outlet, switch, telephone and/or blank slot. Also included are single/double Fast Cap outlet trim rings, 2 countertop outlets and 2 Grommets (60mm & 80mm). You can place the outlets on the inside or outside of the cabinet and turn the outlets horizontally. Plan, elevation and section draw tokens are included. These will be included in hardware reports.

Enjoy!
