Berker socket - what size hole saw?

[CraftyPete]

Hi there

I’m going to be fitting a 240V AC socket and a 12V DC cigarette style socket this weekend. What size hole saw do I need for this job? These are Berker sockets.

In addition, I’ll fit some dashboard style plain old barrel 12V DC outlets, in places harder to see - I think I remember 22mm for this, am I correct?

Techno would advocate using Hella 12 volt plugs and sockets as being superior to cigarette style sockets which can vary in size from manufacturer to manufacturer and so plugs/devices don't always fit!

I took his advice years ago and have been very pleased with my Hella sockets which tend to be standard fit on German vans
