Bs4293 Rcd?

[Blue Duck]

Feeling a little dumb today...... :coffee

I know that these BS4293's are obsolete and no longer comply but I read that if an RCD does not comply with 61009-1 / 60947 but still meets disconnection times they can be used????

It would save me the ball ache of trying to persuade a customer that does not want to spend money to spend money on something that she has no idea about.

Left me regs/osg at home as I have a day in the office

Thanks

Try this;

PDF]RCDs - NICEIC

BS 4293 has been superceded and is not mentioned

as still current in the BGB.

HTH.

 

[Technician]

According to this PDF BS4293 devices are not precluded

PROVIDED that they meet the required disconnection times.

The illustrated one looks like a wylex.

 

[Andy™]

also, BS4293 have different trip times to 61008 / 61009

 

[Sidewinder]

BS4293 devices are obsolete, however, if fitted and test OK they DO STILL COMPLY.

Same as 1361 fuses, you cans till fit these today if you can get them!

4293, disconnect 200ms

61008/9 300ms

As soon as the EU gets involved, things get worse...

Thanks for the help Gents  Guinness

I thought I had read it in the regs but got confused as it also mentions OCPD's  :yawn  And wanted to be sure.

The device is a wylex but don't think its delayed so 200ms is the time to beat and how I do a 2x I delta N I have no idea.? h34r:   I will give it a go at 1/2x, 1x & 5x

 

[Sidewinder]

What do you want to do a 2x for?

What do you want to do a 2x for?

* If the device does not operate within the disconnection time required by

BS 7671, it will be necessary to re-test the device using a current of at least
2 I
Dn
to verify operation (see Table 3A of BS 7671).

 

[steptoe]

if the device doesnt operate within the time specified for x1 I would fail it.

 

[Sidewinder]

I would also bin it, if it fails the x1 test, the rest I'll come back to later, out all day.

Try to keep the thread at the top someone so I can find it, please!

Cheers

Free bump for snakes  

This is on an old shower install the customer is of the non spending variety, even quibbled about spending £60 on a new shower headbang

Will test the RCD won't be happy if it fails 1x and ramp tests In the bin it will go. Its annoying as the supply comes off a henly into the rcd then into a switchfuse!! - if only it was the other way round

 

[Sidewinder]

OK, smart Canoe, last time I did that I ended up with loads of emails telling me people had posted, not what I wanted!

Anyway.

Bluey, your quote in post 8, is from where please?

I guess its old? mentions 61008's or maybe a typo?

 

[Andy™]

ah, the NIC say it, so it must be right...

 

[Sidewinder]

OK, Bluey,

"Read" the wording carefully!

It may be old, not sure my PG25 is in the hire car, which Mrs SW is currently thrashing around the roads of South Wales!

So, I can't check if there has been an update.

By the by.

It is the "2x" comment that you are querying, yes?

There are two ways to look at this & to do the test.

Use one of these, http://isswww.co.uk/17th-Edition-Testers/Fluke-Testers/Fluke-1653B-17th-Edition-Multifunction-Tester-Professional-troub/, or these, http://isswww.co.uk/17th-Edition-Testers/Fluke-Testers/Fluke-1654B--Free-30Mtr-Wander-Lead/, where you can set the test current!

Or do as it says in the PG, "literally" and check at, at "LEAST" 2x, in our case 5x which meets the criteria of being at "LEAST" 2x which we can easily do with most MFT's?

Does this help?

BTW, 61008's are still current.

Whilst Andy is NIC bashing, for once, perhaps, what they say is actually correct!

When you actually "read" the detail of the statement & compare it with the requirements...

 

[Blue Duck]

Sidewinder, thank you for the advice

I am guilty of skimming over it and skipping to the table and not reading the wording correctly.  :facepalm:

Not sure where I got the idea that 61008's were old? headbang  I suppose  they have been over taken by rcbo's but never the less I was wrong  :C

On the last hire car I had the clutch smelled of Garlic

:coat

If it is any help that statement about 2 times

 is in

pocket guide No 25 issued by the NIC.
