Are non switched sockets allowed under BS7671 or are they a code 4?

[ChristianG]

I have come across some non switched sockets and believe they will need to be changed or is it a code 4?

Domestic property.

I am going to look through the book tomorrow, just one of those things bugging me.

Going to have to move the shower isolator too, pull cord is just on the edge of zone 1.

Thanks for any advice given.

No problem in using them at all, I install them under kitchen worktops for low level appliances isolated by FCU's

They are good isolators for central heating boilers as well
The only code I could give them is TAQH

They are quite handy

 

[ChristianG]

Yeah I have used them with fcu as someone didn't want flex outlet plates used before. Thanks for the advice and help.

Non switched are fine to use, but for general purpose sockets in the lounge,hall kitchen, bedrooms I always like to see a switch on it but if fed from a spur non switched is fine and cheaper. Reg 553.1 has details.

what about unshuttered sockets...i've found about 50 so far this week

UNshuttered, or just stuck in the open position?

If the latter Id code 4, but depending on location could be a 1 for a creche!

Ok what about double pole sockets and single pole sockets what code and should it be more clear what socket it is

Depends on the scenario.

Would only be a code if there was a requirement for all poles to be isolated...such as sockets fed from a CT transformer.

 

[Monkey]

Were when and why could you give a sample please

 

[Deleted member 9648]

A safety supply unit in a school lab.....fed through a CT transformer both poles at sockets will be at a voltage of 115v to earth,therefore it is essential that all accessories are double pole switched.

It is a common misconception that socket outlets need to be switched. There are four reasons for switching: -
Isolation
Emergency switching
Mechanical maintenance
Functional

A plug and socket can achieve all of these by simply pulling the plug out so unless you are unable to remove the plug then no switch is necessary. It is only when the plug can not be removed and / or it is supplying an integrated appliance then switching needs to be considered and this may require a switch above the work surface.

Hope this helps
