I have two cu,s one mem 7+7 split load for house and another small cu for garage.swa 6mm cable is burried underground .I also bought two sets of glands.Both cu,s are plastic insulated.Sparky is going to instal main cu in few days time.In my last meating with him,he said glands can not be fitted on plastic cu.it has to be fitted on metal one.Or swa cable has to be fitted into separate metal box and then into cu.How is this done.MEM cu 2000 AD fitted on wall directly,will it have enough space behind to feed cables through such as 6mm swa or 10mm shower cable.Can,t they be fitted on some sort of wooden frame so they have enough space to feed cables from underneath in future.Sparky says they should be fitted on non combustable things.What are they.

Sparky is talking out of his anus. Sack him.
Consumer units look ****e (IMO) on wooden boards. They are desgined to mount directly on walls these days.
The MEM CU's cover, when removed, leaves a skelaton of a CU onthe wall, with no where to gland an SWA into, so I agree, I metal clad CU would be better. However, 6mm could pass through a 20mm through box first.
Why do people always feel they have to by kit for sparks? Sparks do now best as to what is required, generally. You don't take tyres and oil to the garage when your car gets services.......actually, I bet some do.

The reason i bought swa cable and set of glands myself is sparky was unwilling to go into the crawling celler so under his instructions i have to lay cable myself to garage.He even said plastic CU is fine.Now i have bought plastic CU and how SWA cable can be connected to CU.What do you mean by saying,6mm cable could pass through a 20mm box first.Lectrician said:

It must be nice to pick and choose what parts of the job you do. I bet he doesn't do hot lofts or dirty sheds either!
Saleem,
As plugwash says ,your electrician will be terminating the SWA in a 20mm galvanized box with a screw on lid and butting it to your plastic C.U.
Depending on the quality of the plastic that the C.U is made,,or the weight/angle the SWA is terminated it can put strain on the C.U walls and weaken it so it is (in my opinion) best to use the galvanized box method.
