cable burn out

[chloebear]

I have a site where a large number of circuits were rewired about 4 years ago in LSF twin/earth. these circuits include lighting, showers, sockets etc - all fairly standard stuff on the face of it.
Problems have developed over the last 6 months with cable burn-out on certain accessories - 2x light fittings have burnt out the fittings at the terminals, a shower isolator (50amp) has burnt out & a fan heater has caused fairly serious fire.

Seems too random for poor workmanship - I am now starting to think along the lines of sub standard cable.

anyone out there come across this as an issue & what would be he best way to test for this?????

Why?
Bolted terminals have worked perfectly well for decades, if you tighten them properly there should be no issues. OK, the cheap cack has rubbish bolts but as long as you use a decent brand you'll be fine?
I think your idea will be used as an excuse for poor workmanship

the bolted terminals damage the conductor, besides we could all get home/pub quicker.

Perfect reason, I'll back your idea fully

All I need now is a trained snake to pull the Liquorice through the walls/floors.

Wagon connections is a top idea simlec, I do like that idea as it would prevent unnecessary pressure on the cable causing them to snap, nice and easy to install.

It will only handle heat the same as none LSF T+E.
The magic happens when you set fire to it.

My point was it had handles heat far worse than I would have expected twin to have handles it in the same situation.
