After doing some fatal damage to a rather nice piece of test equipment when i was an appretice (many years ago) ALL my test leads are fused at 500mA,

In regarg to signage i have to agree will Paul,

most of the time in large commercial / industrial you will find the signage is usually there, but sometimes (ok most of the time) another sparky has come in and done a bit here and a bit there, added an otlet there, taken a supply from hear, wired another piece of equipment from another supply and low and behold what is written in the panel is not what is installed in the building !!

As we specialise within the liesure industry, Bars, nightclubs etc, they are the worst !!

its like ` lets see who can do this the cheapest` and when it goes wrong, then they call the proffessionals in!!

C H, if 415 jumped out at me, i think i should have to go and seek proffessional advice from my local shrink !!!

But on another topic, slightly, i have had a 100a Three Phase isolator explode at me, we contacted the manufucturer and they said it was a design fault !! took a few years of me i can tell you. !
