I though plastic bags were bad for the environment

They should be using paper bags surely
 
It really is out of control they will want us to make it fully air tight and pressure test it before were done

I was told initially sometime back that the consumer units need not be sealed because the main accelerant was the plastic CU so the steel CU was enough to stop a spread of fire, my question at the time was if the plastic CU were to be replaced with steel what about the MCB and plastic blanks why are they not being replaced with a fire proof alternative.

The answers I've been told is, the fires start from loose terminals in the tops of MCB's and the flames melt the plastic CU which spreads the fire, so any opening below the top of the CU doesn't need sealed, hence the reason why I bring my cables in through the back knock outs and I only put flexible grommet strip round to stop damage to the outer sheathing.

An alternative I was told about was to install a length of deep trunking along the top of the CU and run all cables into the trunking through the knockout in the top of the CU but I'm skeptical that that would work.

I personally don't like the look of loads of glands poking out the top of a CU I prefer them to come out the back.

I would love to meet the people that make these rules. Admittedly I like the metal boards a lot more than the plastic ones as they had a real cheap feel to them but it's getting over the top. Have to be careful with the rest entry through wood because wood burns can't win going to have to carry a sheet of fire board with me now as well as all the other rubbish
 
I like the idea of the plastic bag full of water in the top that would make a great sprinkler system
As has already been intimated......don't give them ideas for the amendments.;)
