Metal Consumer Unit, 10 Way, with 100 A Double-Pole Isolator

A compact metal-clad consumer unit for a campervan, motorhome, boat or cabin mains system. The 100 A double-pole isolator is already fitted and wired, so you add the double-pole RCBOs your circuits need. Its 10 outgoing ways take up to 5 of our 2-module RCBOs.

What we now fit on our panel builds

MCG metal consumer units are what we now fit on our own Victron panel builds, and they are the boards you will see in our latest Instagram reels. We chose them for the steel enclosure (non-combustible, as BS 7671 Amendment 3 asks for), the pre-wired double-pole isolator, and MCG double-pole 30 mA Type A RCBOs that switch both line and neutral.

The same MCG range, sold separately: 2-way, 4-way, 6-way, 14-way, compact AC-in unit, 16 A RCBO, 10 A RCBO. Fit RCBOs largest first, next to the main switch, and use Build your board to add the board, RCBOs and blanking pieces in one go, or let our system designer pick the board from what you plug in.

When to choose the 10-way

For a bigger build that runs like a small home: several socket circuits, kitchen appliances, heating and cooling, each on its own RCBO.

With 3 or more ways, this board also works as an AC loads consumer unit: the distribution board after your inverter/charger (the AC-out side of a Victron MultiPlus or Quattro), with one RCBO per 230 V circuit.

Typical uses

• Large motorhome or expedition truck: sockets front and rear, induction hob, air conditioning, Truma Combi and a water heater
• Widebeam or liveaboard boat with separate galley, cabin and engine bay circuits
• Horsebox living area, tiny home or off-grid cabin with room left to add circuits later

What goes in it

RCBOs are sold separately: our 16 A double-pole RCBO suits the hook-up supply and socket circuits, and our 10 A double-pole RCBO suits lighting or a single fixed appliance. Fill any unused ways with blanking pieces so no live parts can be touched. Not sure which cable each circuit needs? Our cable size calculator sizes the cable for each 230 V circuit. IP20 means it must sit inside a dry cupboard or locker. Mains work must be installed and tested by a competent person to BS 7671.
