blade thickness, 13A plug earth pin ?
 

I'm crap with a micrometer - can anyone with one available (or detailed
specs) tell me what the blade width should be of the earth pin of a
standard 13A plug please ?

This has come about because of a cheap AC charger with a plastic earth
pin which I suspect is out of spec - its a bloody tight fit in two
different manufacturers' sockets...

A normal brass pin (if i'm not mistaken) is about 4.1mm wide, but this
seems to be 4.3-4.4mm wide

TIA :-}

Look for "Type G" about 60% down this page.

Just measured the MK plug on my reading lamp. 4.0 x 8.0mm

I think you should make a fuss assuming this is imported rubbish but
still marked BS/CE.

You know what, that's something I hadn't actually checked, but it is
from a reputable UK vendor...

Thanks for giving me the chance to use my recently bought half-price
Woolworths electronic calipers (they look alright to me).

Plastic pin: 0.165 inch. 4.30 mm. Correct fitting.

Metal pin: 0.155 inch. 4.00 mm. Correct fitting.

Sylvain.

A quote from a recent post in the RNIB talking book list:
I have come across 2 power adapters for Victor players with oversized
earth pins which, as a result do not fit sockets correctly.
The most recent adapter pin measured 4.33 by 8.20 mm at the tip and 4.90
by 8.40 mm at the root.
The spec in BS 1363-3:1989 gives the dimensions for the earth pins as
3.90 min to 4.05 max by 7.80 min to 8.05 max, so this adapter is way out
of tolerance.
The oversize adaptors are being taken out of service for H&S reasons.

Thanks for that - I hadn't been able to find any "official" specs or
tolerances for some reason !
