lighting circuits and cooker circuit code 2 or code 4 on a periodic, its a domestic house thanks

Is there a question in there?
What is the observation?

 

[kfelec]

i just want to know when your doing a periodic test on a domestic house if the lighting circuit dosent have rcd protection and the cooker circuit dosent have rcd protection what codes should they be?


sorry about the first message

Normally code 4, however something you should consider is if the cooker panel has a socket outlet, and it is deemed as possible to be used for appliances outside, then that would be a 2.



I suggest you have a read of Best Practice Guide 4

It's all good for reference.

thanks widdler

That's why we are here.

 

[kfelec]

when you say outside appliances do you mean gardening appliances ect?

Theoretically yes, however any portable appliances are accountable. If you were to run a lead out from the house, that lead will need to be on an RCD, and therefore all appliances used will be too, be it a hair dryer or power drill.

thanks again

The "outside appliances" factor is now completely irrelevant - that's no longer in the regulations.

If it has a socket it's a Code 4.

If the cable is less then 50mm from the surface, and isn't mechanically protected etc, it's a Code 4.

How can it be said to "require improvement" when there is no requirement to update existing installations to the latest version of the Wiring Regulations?

er... beg to differ there BAS..

411.3.3 Additional protection

In a.c. systems, additional protection by means of an RCD in accordance with Regulation 415.1 shall be provided for:

(i) socket-outlets with a rated current not exceeding 20A that are for use by ordinary persons and are intended for general use, and
(ii) mobile equipment with a current rating not exceeding 32A for use outdoors.
An exception to (i) is permitted for:
(a) socket-outlets for use under the supervision of skilled or instructed persons, e.g. in some commercial or industrial locations, or
(b) a specific labeled or otherwise suitably identified socket-outlet provided for connection of a particular item of equipment.

I was going to start a similar topic, but might as well tag it onto this one as the answer will help both of us..

would any of the pro's out there care to include some examples of what would warrant the different codes?

I've got the qualification but haven't done any real testing myself.
All I did at the last place was R1+R2 tests and IR tests on the machines which were then fully tested once installed on site..
before that I always subbed to bigger companies that had their own huys do the testing, or who I gave the test results and notes to and they filled in the paperwork re codes etc..
so I've never really done the paperwork..

Sorry - what I meant was that 471-16-01 has not been carried over into the 17th. The default is that all BS 1363 sockets are required to have RCD protection, even those in flats 100 floors up.

i.e. 411.3.3 (i).

I guess (ii) catches, in the main, IEC 60309 sockets or equipment not connected via a socket, and appears to be the replacement for 471-16-02.

 

[ColJack]

except for exceptions a) and b) of course...
