The shower being fed from the dp switch?

Its the first time I have come across this and not sure what to make of it. Have any of you lot seen this before?

 

[Octopus]

is this your idea of Friday night fun?

 

[amckay]

I honestly wish it was

 

[Octopus]

It must be!

 

[amckay]

Well Murdoch, what are your thoughts on the matter? You ever come across this before?

Looks like they have taken a feed from the main switch to feed the shower switch.
Shame that the feed is not taken from the load side.
Is there an isolator between the Meter and the CU?

 

[amckay]

No isolator unfortunately

Providing the DNO's fuse is 60A

EdIt. - Iso fail

 

[telectrix]

then it's a C2 in my book. no single point of isolation. if the shower sub-board was taken from the load side, you might just get away with it, as the 6mm? is unlikely to be overloaded. bad practice, though. if my eyes don't lie, though, there's a spare way in the main DB. why was that MCB not rated for the shower and used?

It would have been better in an Henly block, with proper sized tails, but being as the shower is a fixed load, it shouldnt need overload protection. The supply to it is quite short, so low chance of a fault there.
Not a good install, certainly worthy of a C3. Dangerous/potentially dangerous, not really.
No RCD protection would mean I'd change it - or recommend it to be changed, but Regs wise, I cant really think of a C2 to 'fail' it.

What size fuse is in the shower isolator?

Basically they've used the Main Switch in the CU as a Henly block.
By rights there should be a single point of isolation for the installation.
One option would be to remove the conductors, and place them in the bottom of the switch.
Another would be to install a switch between the meter and the CU.
It may be possible to rearrange things so that the shower switch is fed direct from the new main switch, or perhaps a Henly block could be installed?

Sorry, but definitely a code C2 for me.
Switch off the main switch, and the shower is still live.
