I found this JB in the loft, the mice have eaten the JB cover as well as some of the wiring, but aside all that in your opinion do you think the JB is overloaded?

I'd say that's probably in the hundreds of thousands.Obviously not to some, as there are still probably 100s fitted incorrectly.
I've a preference for both.I would rather be experienced than qualified.
It was in relation to having a choice between Qualified or Experience.I've a preference for both.
Do they have to be stamped MF or just reach the criteria, certainly the Wago box's are not stamped, but do reach the standard, but then are they meant to be maintenance free, the lighting junction box's for downlighter's in a ceiling for instance can be pulled down to change a downlighter and none of the one's I have available are stamped MF.My question was in using them without an enclosure at all.
Also, I think the enclosure would have to be stamped MF if used as BS 5733 Maintenance Free box.

Seems it was added at the last amendment to 526.3.
526.3 Every connection shall be accessible for inspection, testing and maintenance except for the following:
(i) A joint designed to be buried in the ground
(ii) A compound-filled or encapsulated joint
(iii) A connection between a cold tail and the heating element as in ceiling heating, floor heating or a trace heating system
(iv) A joint made by welding, soldering, brazing or appropriate compression tool
(v) Joints or connections made in equipment by the manufacturer of the product and not intended to be inspected or maintained
(vi) Equipment complying with BS 5733 for maintenance-free accessory and marked with the symbol and installed in accordance with the manufacturer’s instructions.
It may be worth having a look on the Wago site, To be compliant when fitting MF Wago It's not just a case of chucking the connections inside and snapping the lid shut, you have to follow the manufacture's instructions including doing the calcs.
There was also a thing about using the proper mount, instead of whacking a screw through it, if I remember correctly.And the cable tie
And the cable tie
Don't dis the cable tie. They make all the difference between my car being roadworthy and not.
I don't think many decent testers would fall for that these days, or do they ?Not so long ago the same was often said about newspaper and isopon.

Well I can't open a Wago box without a screwdriver inserted under the lid and levering the thing open, the lid clips are certainly tough.It's a sad state of affairs when one piddly little cable tie makes the difference between a box being considered maintenance free or not.
