my question.. can a 110v us extension lead handle 220v bulbs if going into a 220v socket (uk)
my reason..i have a ready made grow box from us and im in uk the lead says 110v and bulbs also 110v so have a voltage converter as i have another box i dont want to fork out on another converter as upgrading bulbs to 23w from 13w so want to just run straight into mains with 220v bulbs no messing around with voltage converter..i did try find a uk version of the us outlet bulb adapters but only seem to be 2 types, 1 that bends so bulb facing UP and some dangly thing that just wouldnt work.
please help before i fry my bulbs or myself
you could probably run that amount of draw with speaker wire.....
i am not kidding.
READ AND LEARN.
Voltage is the energy or kind of speed and vibration that power travels through a cable (240 volts per second).
Amperes is the charge that travel through a cable. (could be 1 soldier charging you or 100 soldiers (centurions) charging at you).
i am trying to put this in to laymans terms.
the volts do not matter, as much as the amps, it is the amps that do the damage.
for instance the thick cable that enters your main fuse in your home splits in to two tails that go in to your meter, that thick cable carries 240 volts but................ it carries 80 amps which must use a thick internal core 25mm cable like that.
the main switch on your fuse box/consumer unit is 100 amp.
the tails to the meter are 25mm
(mcb`s are like fuses) too much wattage draw they trip)
your electric cooker is connected through a 45 amp mcb (miniature circuit breaker) with a 10mm cable.
your socket rings are on 32 amp mcb on a 2.5mm cable.
and your lights are on even thinner cables 1.5mm 6 amp mcb.
all these cables are 240 volts.
if you run your lights on a speaker wire no probs, but if you added a 2000w heater the cable would heat up and burn.
the way we can protect individual cables is we use a fuse in a standard 3 prong plug,, for instance we might use a 13 amp fuse on a 1.5mm cable because if we try to add too many watts the cable will want to warm and burn but the fuse will instantly burn and blow.
if we add a 5amp fuse to a 1.0mm cable then less watts will blow the fuse before the wire melts.
very thin cables and lamps likeyours will run on a 3 amp fuse so if the cable stats to burn the the thinner fuse wire in the3 amp fuse will burn before thecable starts to melt.
so you see it is the amount of power we draw from the cable and not the voltage.
they reckon any thing over 50 amps will kill you.
a 240v 6 amp electric shock will give you a hard on.
a 240v 20 amp electric shock will make you cum.
1 240v 32 amp shock will make you shake and tremble with shock.
a 240v 50 amp shock will almost certainly kill you.
( a 12v 300 amp shock you will feel nothing )
a 240v 100 amp shock will make you start tosmoke and burn if you die and stay connected.
now do you understand?
a car battery is only 12 volts dc but can crank over 240 amps to turn a very heavy engine over, so if you have a metal ring on your finger and it shorts the battery ( touches live and earth at the same time) the high ampage would melt your skin to the metal ring but it is only 12 volts so you would not feel a shock from it..
vehicle wires are usually thick wires for the amount of volts.
if a 240v wire is loose it will arc and start to heat and burn.
ifa 12v wire is loose it will flicker at a light or might only click before it starts the engine on the 5th turn of the key
if you touch a live and neutral wire together at 240 volts 32 amps there will be a flash and a very loud bang.
if you touch a live and neutral wire together at 12 volts 230 amps there will be huge sparks and the welding of wires.
this is why vehicles are very easy to go on fire in an accident, not because they carry fuel, they are protected by a series of relays that switch off when they detect an accident, but there are no relays on the main battery leads which start most engine bay fires....they try to put fuses on them but these will never work.
that is why when you hit a wall at say 20 mph your engine cuts out and it takes a little longer to start the car again.
if we could find a way to harness the amps to stop vehicle fires in accidents we would become instant billionaires overnight, ( i kid you not ) and would not be worried about a few plants.
imagine how many amps it takes to turn over and start a rolls royce engine in a huge passenger jet plane.
instant burn up in an accident.
and imagine how many amps a 232,000 volt uk pylon can carry, touch that and the volts and amps will blow your arm off melt your brain and boil your blood in milliseconds.
at the post mortem the coroner will say death by electric shock.
the end.
peace.
