I thought that the maximum operating current was worked out as 50v/Ra=in. Is RA not the resistance of the electrode, which was 100 ohms giving an answer of 500mA?????
Same as, also did the equation but used the wrong resistance ( I think ) , this is what happens when you take a 8 year break from electrics and the boss dumps you in it !lol it was a 10 point question so Automatically assumed it was a 30mA as you only do a couple of tests for the other RCD's no 5X Tests
Silly quote of the day, just before I leave for my exam my Mrs says "knock em dead babe", I tried to point out that this is exactly what the 2391 is trying to protect against lolololol.......
