Presently visiting Mddle East and need to ask someone familiar with
the UK style 13 amp fused plugs, 230 volt at 50 cycles etc. the
It's been unusually chilly and neighbours using electric heaters have
used what it is understand are called 'Power bars' each with or
without switches, some small indicator lamps/neons and several
outlets. Due to poor quality (possibly made in some people's
republic?) a couple of these have caught on fire! Fortunately without
So instead we recently wired up some substantial single outlet
extension cords using brand new allegedly UK made 13 amp plugs, 2.5 mm
three conductor cab-tyre cable to a single three prong outlet mounted
in a plastic approx four inch square box. All material was brand new.
All connections are new and good, the stranded wire ends being tinned
with solder and secured tightly under those little brass screws.
Arrangement made to avoid any chance of pulling the wires by double
tie clamping the rubber cable sheath to the box. The 13 amp fuse
holder is tight and new.
Testing one extension, about 8 feet long, with a 2000 watt small
blower heater surprised to find the plug getting 'quite warm' but not
hot after a couple of hours! This normal?????? The wire 'cord' is not
the least warm to the touch.
It seems to be mainly the plugs that are getting warm; each plug has a
solid brass earth/ground pin. The neutral (Blue) and live (Brown) pins
are partially brass and partially brown plastic. They look exactlty
like all other 3 prongers used for 230 volt here.
So 2000/230 = 8.7 amps; load mainly resistive with a few watts for the
fan blower. So well within the 13 amp rating; eh? One reason to ask is
that in North America we routinely take up to 1200 or 1500 watts (at
115/120 volts = approx 10 amps) through North American style, unfused,
three prong plugs that appear to be less substantial and contain less
metal etc. than the UK version. And I don't recall they (normally) get
warm. Unless they or the outlet is faulty.
Any comments/advice please?
