With all due respect to someone who would make a safe connection... just no buried boxes with connections...
I've read about some shortcomings with Wago connections having to do with the spring connectors in them.
At no point did you read that
I was promoting Wago.
I don't like added connectors, full stop. However if I had to specify that a connection was used, it would have to be something that is to a relevant local standard.
Whenever a Septic, hears someone critical of the wire nut connector, they start to attack Wago? I'm always puzzled why.
Wago have ratings that shouldn't be exceeded, and can be a failure point but where applicable are an OK option, they don't fracture the wire if removed, and don't leave damaged ends on the conductors.
Were you aware that the ability to periodic electrial testing is sometimes required on the mains wiring of UK residential property?
Wire nuts are not "to code" as you would say, and if you were renting a property to someone, it would fail the instalation testing if any were found in use, basically at a minimum, the installation has to be subjected to the test at each change of tenancy.
Buried and inaccessible connections in domestic property is forbidden, but so is a lot of things people still do, the point is mute because
it isn't necessary, and shouldn't and doesn't have to be be done. Many of the problems associated with UK private properties electrical systems are caused where unskilled owner occupiers have modified their own installation, (also illegal unless a qualified test and inspection has been carried out afterwards), or where old systems have fallen into disrepair, and power carrying
joints have become loose and overheated.
The employment of a general factotum/handyman to do electrical wiring without proper qualifications is to share responsibility for any problems that arise, and people who work on electrical, gas, or class 1 combustion heating systems without suitable up to date qualifications,
regardless of blame, are risking imprisonment.
