Buried in the wall, no. Requires a complete assembly complying with BS5733 MF which will incorporate strain relief etc. Note that most insulated crimps are not suitable for solid conductors.
Is it that it's not suitable or that the standards do not mention solid conductors?Buried in the wall, no. Requires a complete assembly complying with BS5733 MF which will incorporate strain relief etc. Note that most insulated crimps are not suitable for solid conductors.
Is that a photo? It looks great if it is. I use the oval stuff quite a bit where people want extra sockets in decorated rooms. I have been quite lucky with getting the cable between dabs and just using the trunking horizontally.Final throw of the dice - show them D-Line semi-circular trunking. It is much nicer on the eye. I even skimmed over and lightly sanded it once to make it look like it was part of the original plaster cornice in a national trust property.

I know more than I want to about this following an argument with a CPS.Is it that it's not suitable or that the standards do not mention solid conductors?
And how is a crimp or solder connection any less likely to be pulled apart whilst plastered in than a socket? A lot of this BS is trying to do the thinking for people and make money from it. I believe the wago boxes need to be installed in free air and fixed with the silly button thingy too.I know more than I want to about this following an argument with a CPS.
BS5733 MF has a list of 10 tests for an assembly to be suitable for MF joints.
A crimp wouldn't comply, nor would any single connection device be it a wago, ideal connector, choc bloc, etc. as the standard includes strain relief for the cable, needing a tool to open, being marked MF and a load of other stuff.
That is why I say above that an ideal connector cannot possibly comply on it's own.
Wago, and now Ideal have jumped through all the hoops and their enclosures and connectors together comply with BS5733 MG if you follow their precise instructions.
Stop reading now if you don't like sarcasm.
Previously Wago boxes and connectors only met the standards below so obviously this was totally inadequate:
Mechanical Tests.
* Pull-Out Test to IEC/EN 60947-7-1, IEC/EN 60998-2-2, IEC/EN 60999-1
* Shock Test to IEC/EN 60068-2-27, 60068-2-30; Railway Applications IEC/EN 61373
* Vibration Test to IEC/EN 60068-2-6; Shipbuilding GL, LR, DNV; Railway Applications EN 61373
Electrical Tests
* Temperature-Rise Test to IEC/EN 60947-7-1, IEC/EN 60998-1, IEC/EN 1-61984
* Derating Curve to IEC/EN 60512-5-2
* Voltage Drop Test to IEC/EN 60947-7-1
* Short-Time Withstand Current Test (Short-Circuit Withstand Capacity) to IEC/EN 60947-7-1
* Insulation Parameters to IEC/EN 60664-1
* Power-Frequency Withstand Voltage Test to IEC/EN 60998-1
* Rated Impulse Withstand Voltage Test to IEC/EN 60664-1
* IP Ratings for Electrical Equipment to IEC/EN 60529
Material Tests
* Needle Flame Test to IEC/EN 60695-2-2

Environmental Tests
* Temperature Cycling Test to IEC/EN 60947-7-1, IEC/EN 60998-2-2

* Salt Spray Test to IEC/EN 60068-2-11, Marine Applications GL, LR, DNV
* Quick Change of Temperature to IEC/EN 60068-2-14
You'll be glad to know that they have now passed the newer 10 point test so we can use them after all.
And how is a crimp or solder connection any less likely to be pulled apart whilst plastered in than a socket?
