The electrician was there before the kitchen planner. The sockets sit where they made sense during the shell construction — and years later the kitchen stands differently from what anyone assumed back then. In existing kitchens that is the rule rather than the exception.
The case in question looks like this: the fridge or the oven housing unit stands in its place. The socket that belongs to it, however, sits not behind the appliance but in the building wall behind the neighbouring cabinet. The appliance still has to be connected.
Why this is a problem at all
As long as the kitchen is in place, the socket is out of reach. It lies behind a screwed-on carcass back panel, and in front of that stands a cabinet full of contents. During connection this is still manageable — you can get to it before everything is fixed.
The service call comes later: the appliance is replaced, a fuse blows, someone needs the socket for something else. And then you stand in front of a panel knowing exactly where the socket is — without being able to reach it.
The socket stays where it is. Only the access to it is created.
The objection that always comes up
“Then just move the socket into the back panel of the neighbouring cabinet.” This suggestion comes up reliably, and it sounds reasonable. It still does not solve the case.
First, an existing socket in the building wall cannot be moved without electrical work. Anyone relocating it is working on the fixed installation — a different job from a kitchen installation, with different effort and different responsibility.
Second, and this is what most people overlook: a new socket in the carcass back panel then sits inside the cabinet. It takes up storage space, it gets in the way, and the appliance cable then has to run through the cabinet interior instead of out of sight through the cavity behind the back panels. An access problem turns into a permanent space problem.
So the customer pays for electrical work in order to end up with a cabinet that can do less.
What the requirement actually is
The socket does not need to be moved at all. It may stay where it is. What is missing is only one thing: access to it that stays closed in everyday use and opens when someone needs to reach the plug.
In practice that means: at exactly the point where the socket sits behind the back panel, a hole is cut into the carcass back panel of the neighbouring cabinet. A mounting frame with a lockable cover sits inside it. Closed, you see an unobtrusive disc in the back panel. Opened, you reach straight for the plug.
The storage space is fully retained, the cable still runs out of sight behind the carcasses, and nothing about the fixed electrical installation has been changed.
What matters in execution
The position follows the socket, not the appearance. Mark the position of the socket before screwing on the back panel. A few centimetres off means that later you have the opening but still cannot reach anything.
Large enough for a hand. A 125 mm hole is enough to reach a plug by hand and pull it. Noticeably smaller turns it into an inspection window with no use.
Reclosable, not screwed shut. A screwed-on panel serves its purpose exactly once. At the second service call it gets unscrewed again, and at some point the screws are missing.
In everyday use an unobtrusive disc in the back panel. The marking shows which way it releases.
Matched to the panel thickness. Carcass back panels are usually between 3 and 19 mm. A component that covers only one thickness only fits some kitchens.
Background
The RP01125 exists for exactly this task: a two-part, twist-locked access cover for 125 mm holes in furniture back panels, designed for material thicknesses from 3 to 19 mm.
A related case, where the same opening has to be closed for a different reason, is the recirculating downdraft extractor.
