Washing Machines Failing PAT tests on High leakage

[martinxxxxxx]

I have been asked to test some washing machines and they are all failing on high leakage current.

I passed the course 2377 but cannot remember if there was any lee way on this test, as I remember it is 0.75ma max handhel 3.5mA (All others)

But what if it is just over that figure?

Thanks

Martin

Look in your copy of the IET Code of Practice, that you must own if you passed C&G 2377.

Look, I can see from your previous post that you are a Ban wannabe.
(Edit N.B. I think you will find that BAN saves this kind of treatment for people doing foolish things with electrics that are beyond their current level of understanding - not for people who simply are getting results that they want help in interpreting in their normal course of work :end edit)

But it is really sad.

You know you will never get thanked for that kind of post and you are only on 4 so far.

Pretty unpopular aren't you?

I have consulted various publications and reminded myself. But you could have help instead of making cheap snipes.

Sad so sad, that society produce people that just want to kick people down. What is the use of that.

Table 4: Additional requirements for equipment having higher leakage current
Permanently wired or supplied by an industrial
plug and socket-outlet
Protective conductors
Label The equipment should have a label bearing
the following warning or similar wording
fixed adjacent to the equipment primary
power connection (based on clause 5.1.7 of
BS EN 60950)
The equipment should have internal protective conductors of not less than
1.0 mm2 cross-sectional area (based on clause 5.2.5 of BS EN 60950), and
The equipment shall be permanently wired to the fixed installation, or be supplied
by an industrial plug and socket to BS EN 60309-2 (BS 4343)
WARNING
HIGH LEAKAGE CURRENT
Earth connection essential
before connecting the supply

From memory the leakage test is not a "compulsory" test. If you carry out a class1 IT test for example it will not perform the leakage test at all.

Keep in mind that you may need help/advice from the forum in the future. I read your post as unhelpful at best and possibly rude. If I can read it that way then others are likely to as well. It is sometimes worth remembering why you signed up? Was it to be helpful and occasionally get help?

Yawn.

I have consulted various publications and reminded myself.

Well done.

But you could have help instead of making cheap snipes.

No, I don't think I could have.

Should've been a question mark at the end of that sentence.

No, I don't think it was.

PS. don't feed the troll (me, in this instance).

No need to tell me, I'm not likely to send you food parcels anyway.

It was a question not a sentence! Sentences have full stops at the end of them so it does not make sense to say
"Should've been a question mark at the end of that sentence."

What you mean is

"Should've been a question mark at the end of that question."

Trolls in glasshouses

It's still a sentence (an interrogative sentence to be precise).

Get back to school.

No glasshouses here, chum.

Yes there are Pedigree

Anyway anyone got an idea for these high leakage current washing machines?

Martin, I know nothing about PAT testing, not something we have taken on as a business or trained for. But I assume the 0.75mA is a leakage current? If it is then it seems to me that it might be related to the washing machine heater element and quite typical for a machine which might be a couple of years old and certainly not enough to trip an RCD. Assuming it is leakage then a rough calculation 230/0.75mA > 3Mohms.

30 years ago we simply checked the physical condition of the equipment, checked the fuse rating, tested earth continuity and insulation resistance.

EDIT, we used to pass anything at 1Mohm or better.

As an aside, I see these days that the earth continuity appears to be done at high currents??

These are NEW machines! And some secondhand ones too.

This is the entire stock of a washing machine hire company - so far none have passed.

Different brand of washing machine.

Three different testers have been used (all of which are "in calibration")

One has be returned ( the newest one) to Kewtech for the manufacturer to check the calibration. We await the result......
