RE: internet information (worldwide electricity supplies)

[Victor L. Boersma]

I haven't checked the WEBsite (I avoid visiting WEBsites unless there is a
terrible need to know) so I don't know what exactly is there.  However,
quite
often, the useful information to have is what the permissable variations in
the Electrical supply are in various parts of the world.  At one time I had
such
a list for North America and it helped considerably in product design.  My
understanding is that with the privatization of the North Amercan
electricity
generation and distribution, the private sector operators are now
establishing
norms for how much deviation they will allow in the "DESIGN"
characterisitics
of a power generating and/or distribution entity, before they will let such
a 
[provider connect to their network.  (Supply contracts tend to have
terrible
penalty clauses for the power going down or off).

These norms overall, are not in the public domain because the operators of
all manner of networks have come to the realization that too much standard,

makes their facilities more vulnerable to cyber attacks.

Laura,

The gauge you listed is 0.75 sq-mm which is suitable up to 6 amperes according 
to IEC 60335-1. Also, check EN 60799 for more information on cord sets. 

BTW. Who is your cord set supplier?

We are trying to determine the proper fusing for the UK power cord.  The
products we will be using the cord set on will never exceed 3amps in normal
operating conditions.
For the power cord set the Manufacturer has provided us with the following
information:

BSI/ASTA Approved
British Male to International Female,
HO3VVF3G0.75
Unshielded, Length: 8', Color: Black.

The Manufacturer has asked us to specify a fuse of either 5A or 10A,  with
the information above how can we determine on whether a 5A or a 10A fuse
should be used being that the gauge was not listed?
Thanks a lot for the previous help and also thanks in advance for any help

BS1363, table 2 gives the maximum fuse rating for certain sizes of cable.

Cord sizeRated current  Fuse rating
0.50mmsq  3A  3A(5A)*
0.75mmsq  6A  13A
1mmsq  10A 13A
1.25mmsq 13A  13A
1.50mmsq  13A 13A

*The figure in brackets indicates the fuse rating when a non-rewireable
plug/cord assembly is used with certain types of equipment where the use of
a 5A fuse link is necessary because of high instantaneous input current.

There would be no problem with fitting the plug with a 5A fuse provided it
can withstand the inrush current of your product.

RE: internet information

[Crabb, John]

Sorry to add to the confusion, but the British trade 
association FEI publishes a document on periodic 
safety checks for business equipment, which includes 
a table of conductor sizes and fuse sizes
for British plugs, with the following note:
"BS 1363 specifies only the use of 3 A or 13 A fuses. 
Conditions applicable to using a 5 A fuse with a 0.5 mm2 
conductor are given in BS 1363."

This seems to tie up with my (old) copy of BS1363, 
which specifies a 3A fuse for 0.5mm2 cord, and a 13A fuse 
for 0.75, 1.00, 1.25 and 1.50 mm2 cords. 
Adjacent to the 3A fuse rating for 0.5 mm2 cord is (5);
with a note that "the figure in brackets indicates the fuse
rating where a non-rewirable plug/cord assy is used
with certain types of equipment where the use of a 5A
fuse link is necessary because of the high instantaneous
input current".

If anyone has the latest version of BS 1363:1984, or 
BS 1363:Part 1:1995, they could confirm the above.
I note that in the BSI catalogue, under the entry for 
BS 1362 (fuses for BS 1363 plugs), it states 
"for use in plugs complying with BS 1363, the preferred
current ratings are 3A and 13A.

RE: internet information

[Raymond . Li]

Hi Laura,

You can fit a 3 amp fuse in the fuse safely unless you have other technical
specification on your product, i.e., high inrush current required.  With
0.75 sq mm cord given, the maximum permissible current is 6A but the
harmonised standard allows 10A in line with other European countries.  I
also take a note from BEAB saying that 13A fuse is allowed with 0.75 sq mm
cord on their approved products.  However, no specific explanation was
given.  Hope above information is useful to you.

Practically all UK domestic premises and the vast bulk of UK low power
single
phase outlets in commercial and light industrial premises use plugs and
sockets to
BS1363. They is a legal requirement for all new installations in domestic
premises.
If you have not come across them, they are jumbo sized square 3 pin plugs
rated at a
modest 13A. An essential part of the specification and design of this plug
is that
it contains a fuse to BS1362. As far as I am aware this design of fuse is
not used
anywhere else.

The normal way to wire up domestic premises in the UK is to use a ring main
system.
Typically all the socket outlets on each floor are connected to a ring of
two
conductor plus earth cable that runs from the fuse box around the rooms on
that floor
and back to the fuse box.

Heavy current devices such as cookers and water heaters are wired
separately
as is fixed lighting.

Each ring main is protected at the fuse box by a fuse or circuit breaker
that is rated
for the wiring of the ring main, typically 30A or 50A.

A large proportion of electrical fires in domestic premises are caused by
damage
to the power cord between the wall socket and the appliance. If the
insulation
of low current rated power cords is damaged it is quite possible to have a
partial
short circuit in the cable that allows sufficient current to flow through
the cable
to cause serious overheating without taking out the high rated fuse
protecting the
ring main. Since this current is not flowing in the appliance, the fuses
there are of
no help.

In industrial wiring practice it is normal to insert a fuse or breaker
every
time a
low current rated spur is taken off a higher rated feed at the point it is
spurred off.
In this way all cable is protected by a fuse appropriate to the rating of
the cable.
This principal is extended to domestic wiring in the UK.

Because it is not known in advance what the rating of  the power cord
plugged
into any wall socket will be, the fuse cannot be fitted in the socket. It
is
therefore
fitted in the plug. This system has the advantage that low rated cords can
be used
safely for low rated appliances.

You ask how to distinguish between ring and spur circuits. This question
does not
normally arise for suppliers of equipment to the UK market. UK law requires
that
all electrical appliances sold for domestic use are sold with a power cord
fitted
with a BS1362 plug containing a fuse appropriate to the rating of that
power
cord.
These regulation also cover thing such as office equipment and personal
computers
that might reasonably be bought for domestic use.

I hope this helps clear things up a bit for you

Regards
Nick Rouse

RE: internet information

[Raymond . Li]

Hi John,

Sorry to ask such a big question.  In fact, this is my first time to hear
such technical explaination about why UK plug must be fused so I believe I
can ask a right person for this question.  In the past, I got a common
answer from UK people saying that the UK mains plug is the most safe plug
in the world as nearly no other plugs are equipped with fuse, i.e., US
plug, VDE plug.  Now I know there is other reason behind.  Anyway, I deeply
appreciate you have given a number of sources for my reference/study.

Best regards,

I think you have asked a very big question - and unfortunately I do not
have time to go into it!

However, I also think that it has been discussed before in EMC-PSTC, and so
I suggest that you ask Ed Price or Rich Nute if they can identify the
previous threads for you to examine on the RCIC website.

Additionally, I would recommend that you try the Interpower Components
website (www.interpower.com) and request a copy of their "Export Designers
Reference and Catalogue 9".

Page 16 thereof gives a brief resume of the need for fusing in UK BS1363
plugs.

You could also review BS 7671"Requirements for Electrical Installations" -
otherwise known as the "IEE Wiring Regulations" (which I believe you may
use in Hong Kong) and its associated Guidebooks.

All UK standard power cords require to be fused - regardless of the fusing
in appliance to which they are connected - because we use a totally
different building "ring main" supply system to most other countries which
use "branch" or "spur" systems !

The main reason is that the power cord cross-sectional  (0.75 - to 1.5 sq
mm) area is much less than that of the ring main (2.5 to 4 sq mm) , and
fuses have to be inserted wherever such a change occurs.

Fusing in the appliance is to protect the appliance - not the power cord.

Hi Laura.

You mention wire type:


This looks like 0.75mm2 cross section area cable, and should be protected
by a 5A fuse.

RE: internet information

[Laura Leyba-Newton]

We are trying to determine the proper fusing for the UK power cord.  The
products we will be using the cord set on will never exceed 3amps in normal
operating conditions.
For the power cord set the Manufacturer has provided us with the following
information:

BSI/ASTA Approved
British Male to International Female,
HO3VVF3G0.75
Unshielded, Length: 8', Color: Black.

The Manufacturer has asked us to specify a fuse of either 5A or 10A,  with
the information above how can we determine on whether a 5A or a 10A fuse
should be used being that the gauge was not listed?
Thanks a lot for the previous help and also thanks in advance for any help
you can give me,
-Laura

Re. the power cord.

SI No.1768 requires UK consumer products to be fitted with a
plug conforming
to BS1363.  Both BS1363 and SI 1768 require the plug to be
fused.

The fuse value is determined by the cross sectional area of
the power cord
conductors.

I doubt that you could find an unfused UK power cord set
anyway.

Hope this helps

I think you have asked a very big question - and unfortunately I do not 
have time to go into it!

However, I also think that it has been discussed before in EMC-PSTC, and so 
I suggest that you ask Ed Price or Rich Nute if they can identify the 
previous threads for you to examine on the RCIC website.

Additionally, I would recommend that you try the Interpower Components 
website (www.interpower.com) and request a copy of their "Export Designers 
Reference and Catalogue 9".

Page 16 thereof gives a brief resume of the need for fusing in UK BS1363 
plugs.

You could also review BS 7671"Requirements for Electrical Installations" - 
otherwise known as the "IEE Wiring Regulations" (which I believe you may 
use in Hong Kong) and its associated Guidebooks.

John Allen

All UK standard power cords require to be fused - regardless of the fusing
in appliance to which they are connected - because we use a totally
different building "ring main" supply system to most other countries which
use "branch" or "spur" systems !

The main reason is that the power cord cross-sectional  (0.75 - to 1.5 sq
mm) area is much less than that of the ring main (2.5 to 4 sq mm) , and
fuses have to be inserted wherever such a change occurs.

Fusing in the appliance is to protect the appliance - not the power cord.

Hi John

When I typed that last statement I didn't believe it to be naive but
obviously it was.  I was surprised to find that quite a lot of countries use
"UK type" plugs (see web sites below).  Amongst them is Hong Kong although I
believe that Hong Kong requires plugs to conform to BS1363.

RE: internet information

With respect to the last line of Chris Colgan's email: Be careful!

In the UK we have seen a number of bogus power cords with "13A" plugs which 
have no provision for fuses.

Additionally, they are much narrower than BS1363-compliant plugs and have 
no insulating sleeving on the Line & Neutral pins - so that it is easy to 
get your fingers on the Line Pin as you insert the plug in a socket-outlet!

Obviously they have no BSI/ASTA certification markings and - also obviously 
- they are not legal in the UK!

I believe that our local Trading Standards Officers are aware of the 
problem, but it has not - to my knowledge - received a great deal of 
publicity.

Typically they seem to turn up with very cheap PC cases made in the Far 
East, but they could appear anywhere.

My guess is that they were designed for countries where BS1363 sockets are 
used on radial/branch circuits covered by 15/16A fuses or breakers, and 
where the legal requirements on access to the pins are much less stringent 
than the UK - does anyone know where this might be?

All UK standard power cords require to be fused - regardless of the fusing 
in appliance to which they are connected - because we use a totally 
different building "ring main" supply system to most other countries which 
use "branch" or "spur" systems !

The main reason is that the power cord cross-sectional  (0.75 - to 1.5 sq 
mm) area is much less than that of the ring main (2.5 to 4 sq mm) , and 
fuses have to be inserted wherever such a change occurs.

Fusing in the appliance is to protect the appliance - not the power cord.

Yes.  The UK uses a "ring" wiring scheme such that the
installation overcurrent protection cannot protect the
power cord wires as is done in the North America branch
wiring scheme.  Therefore, to protect the power cord from 
overcurrent, the plug must include a fuse.  (The plug fuse 
does NOT protect the load from overcurrent; this is a 
function of the product fuse.)

Rich
