Indicator light when current is drawn...

Situation is a block of units with shared external laundries. Each unit
has a switch internally that energises a power point in the external
laundry.

Is it (easilyishly) possible to install a lamp (something that clips
into a standard switchplate would be nice) that illuminates only when
current is being drawn through that circuit?

The object being not only a reminder that the circuit is live (via
lamp 'A') but also a convenient tell-tale as to when a run of
washing is complete (ie: when the machine stops drawing current).

(Of course, I'm stuffed if it turns out that the machines draw
current all the time - I will check that!)

TIA,

Perhaps you could adapt a current sensing circuit for automatically
turning on periperals when a computer is switched on. There was one
published in Elektor, July/August 2004 and I've got a feeling I saw a
similar thing in one of the other mags- Silicon Chip or EPE maybe.

I also found one at:

I replace the switch with switch+light (light goes on when switch is on)
but doesn't monitor current


You could look at current clamp meter

This needs to go around one of the wires

I think you will find that poster means an indication inside their unit
so that they dont have to travel umpteen floors to find out

FFS Phil, go back and read the post from the beginning. Apply a bit of
rational thought (hang on that's beyond your capacity) and it doesn't take a
degree in fucking rocket science to figure out the laundry isn't in the
poster's unit.
Without some slight wiring re-arrangement by a qualified sparky would it be
possible to easily monitor that current is being drawn from the GPO in the
laundry, presumably controlled via an isolation switch in the poster's unit.

A number of years ago EA or one of the other electronics mags published a
circuit which could be used to switch on other mains powered devices when
current flow was detected in the a.c mains input to device used as the
"control" appliance.

I couldn't see any valid reason why that type of circuit couldn't be adapted
to detect the significant current that's likely to flow in the feed to the
washing machine whilst it is in a typical washing cycle as opposed to it
being off or having completed the selected program cycle.

The logistics of legally installing one of these devices unless a
commercially available approved device exists, are probably zero.

Alan. If you will keep quoting Phil's filth, you only propagate it further.
Some of us find it objectionable.

If it works so well, buy one to remind yourself to take ALL your

Check your local Bunnings store, they have all manner of "smart" mains
devices like that, so may have something that is suitable.

Current transformers are often used in typical domestic PC UPS
devices, Those that I have seen usually have about 4 turns of wire
round the primary, in series with the load (on one side of the mains
output). The secondary is rectified, and monitored by the UPS to
determine the mains load, so as to act as overload protection, etc.

With a laundry, it probably be wise to use thick wire, due to startup
currents of washing machine motors, and possibility of a washing
machine/dryer being on at the same time, maybe drawing in excess of
20a continuous.
This is a lot more than a typical UPS that might be rated at anything
from 200-1000W

if you are technically minded and know what you are doing in relation
to mains wiring and safety, you could try removing the low voltage
secondary of a typical small transformer from a 240v (ironcore
transformer based ! ) plugpack and replacing the secondary (low
voltage side) with a few turns of 20a rated wire in series with the
load. Im sure you would get a usable voltage from the other side of
the transformer that you could monitor to get an idea of the current
being drawn in the laundry.

Depending on the voltage coming out under load, it could be used to
drive a LED through a suitable dropping resistor.
if the voltage is too much you can have less windings on the primary
(mains) side.


On the other hand you could try Haymans, Turks etc, they might have
something in their catalog that would do this job with much less fuss.


Remember too that since this involves direct connection to fixed
wiring doing this would certainly be illegal, if you arent a licensed
electrician, and even if you were, the device might require approval
etc.
