The relevant regulations are I think as follows:
BS 7671 513.1: cable joints must be accessible except where allowed by 526.3
which is covered by ...
BS 7671 526.3 (iv) joints made by welding, soldering, brazing or compression (which covers crimped connections)
So far so good. But:
526.5 (iii) Every termination and joint shall be in an enclosure partially formed or completed with non-combustible material.
This I think does not cover a choc box which is as far as I can make out is made of polyproplyne which is combustible.
Am I missing something?
I know you will all say I should use Wago connectors in a Wago box which is obviously correct, but I want to know how I should treat existing inaccessible crimped connections in a choc box in an inspection.
