You stated that with one fan speed is correct, but with two it is not ?
Maybe the fan power source is current limited ? So it does NOT have the power to drive two fans. Only enough for one.
if you insist on two fans you need to find another source for your power.
There are no real short cuts to be had,
You must have experience as well as technical understanding,
Now if you have the technical understanding ?
Now you need to get the experience
BUT HOW ?
The time honoured way,
start at the bottom and workup from there,
If you are as good as you claim ?
Then...
DITTO ! has any one approacned the previous sparky in a civilised way and asked him to rectify the faults ?
If not, then it is NOT fair to attack his character.
If the customer decides he does NOT want the previous electriacian involved ? thats a differant matter, and is NOT the previous...
some thing doesnt add up ?
4.5w @ 12v is less than 400ma
where does 1.2A come from ?
unless it's for three or four lights
either way a replacement driver will be available
If the zapper was controlled like an electric fence controller, so that the zap was not fatal then yes I would use it, i don't buy the story about fun loving lads !. If it's not yours then don't play with it, if you play with others stuff and you break/damage then you pay. simple. since we have...
QUOTE - if there is zero voltage at the end of the load, what powers another device if you add one in series?
Current powers the load NOT voltage, your measuring voltage, put an amp meter in the neutral line, then you will see some action.
little grass hopper needs much learning !
most leads with a good solid load on them will heat up a bit,
this is normal, but is it too much ? again a very subjective thing,
All you can do is make sure it's in good condition and if possible able to shed some of it's heat, I E not covered with insulation and stuff.
If the leads rated for...
No easy way out,
with power levels of that magnitude
Low voltage is out of the question, due to costs.
It is possible, but awefully expensive.
Better off using mains power from generator.
More details could bring in more options ?
RCD's are very finiky devices,
they won't tolerate any inter connection between the neutrals and the earth lines on the load side of the RCD.
so go thru all your circuits and make sure all neutral lines are keep completely independant of the earth lines.
