Consumer unit regulations change
A heads-up that Amendment 3 to the wiring regs (due in January) will require
home consumer units to be made of a non-combustable material (i.e. metal), or to be enclosed in a non-combustable enclosure. This follows a five fold increase in 5 years of house fires starting in plastic consumer units, often under the stairs, which are usually the only escape route. This applies to any other switchgear too, not just the CU. The new requirement will be delayed until January 2016, to allow manufacturers time to produce metal consumer units in sufficient numbers. Pleased to say I always throught the thermosoftening plastic CU's were a liability and I have fitted commercial metal ones when I've replaced CU's over the last ~15 years. -- Andrew Gabriel |

Its very funny, cos my old original 1939 one with wire fuses was made of
metal with little bakalite covers for the fuses. Some plastics do not burn but do melt and give off nasty fumes as they do so. I always thought it was a bad idea to use anything that can be toxic.

Answer "For a domestic installation complying with the 17th Edition where all the final circuits are RCD-protected, an RCD main switch is no longer required, provided that the consumer unit is of all insulated construction."

LFB report in 2011 suggested main cause was poor connections to neutral
busbars. See http://www.electricalsafetyfirst.org...ched-On-25.pdf Included: "While the main cause of fire within plastic consumer unit enclosures is without doubt poor workmanship, the materials used in the manufacture of such enclosures and possibly the type and arrangement of the components are other factors that can't be ignored. The increase in the number of terminations having only one securing screw and an almost unanimous adoption of 'cage clamp' type terminations are arguably a backward step in equipment design, irrespective of whether they comply with current product standards." and "Five common brands of consumer unit were selected for the first stage of the investigation. Initial tests showed that only two of the five brands included flame retardant in the plastic enclosure material, although there is no requirement in the applicable product standards to do so." -- Robin reply to address is (meant to be) valid |

Why are the tails moved about? Meter changes? I wonder if the fire investigations listed the tail sizes and type of clamp. And whether they were able to identify the exact source of the overheating. Maybe more flexible tails are an answer. Metal boxes are just about containment not about prevention. If TT installations will need a leading RCD I suppose that will need to be in a metal box too and ........

The other option for TT systems was to provide extra sturdy insulation around the feed on entry and inside the CU before it becomes RCD-protected, and kits were available to do this for some metalic cased CU's.

A change in the fire reporting that indicates an increase but there hasn't really been one. I go for the third ATM. Or a drop in the quality of the terminals. There is a thread on the IET forums about this - a lot of folk are citing poor terminal quality (dissimilar metals and poorly constructed cage clamps that make it too easy to get the wire or busbar prong the wrong side of the cage). I am less than happy with the quality of many accessories. You get screws where the earth in a bit of 2.5mm2 disappears up the side of the screw no matter how you arrange it. Or weak and flimsy terminals. I've had heaters and extension leads where the moulded plug runs hot under full load (hot not warm) - a problem which seems to miraculously go away when I rip the plug off and replace with a nice solid MK one. I have only had one socket do that (all GET plastic sockets here, new 3 years ago) - and that had been abused because someone failed to plug a heater in properly with the plug half out). So to me it suggests that there's too much crap entering the market. Other than gratuitously poor installation or extreme abuse or exceptional failure, no switching device or accessory should be getting hot let alone catching fire. Whilst I don't think thermoplastic CUs are a great idea, they are solving the wrong problem. Higher product standards and random sample testing on an ongoing basis is what's needed. |
