Why neutral? (And why 20 characters in a thread title)?

[davesparks]

Has this always been the case that the neutral seems to be more susceptible than a live, or is it a more modern trend?

I'm just thinking that maybe the increasing use of electronics which can create harmonic neutral currents could somehow be related?

I was thinking along the same lines, but I'm thinking this would only really apply in three phase systems which is why half size neutrals are becoming a thing of the past.

Once upon a time... (before the days of moulded plugs) when I worked as a TV/Video Tech. when checking the plug connections on equipment with intermittent power, it was invariably the neutral that was loose.

Remember that with d.c. current actually flows from the negative to the positive.

It is due to the molecular construction of the flue flue valve.?

i notice it's the neutral at the high load items like showers and cookers. Generally it's a loose connection on the load side, although a decent one was a loose neutral at the actual shower and had burnt the pullcord out as well.

Double sockets tends to be the line that's loose & burnt out.

I think if you combine that with the gyroscopic wobulator synchronisation issues you're onto it ...

Increased harmonics from electronic power supplies, especially in the triplen range could be the cause of higher neutral termination failures. Also poor quality neutral bars with single screw terminations and almost no brass content probably don't help either.

Is it as simple as any muppet with a volt stick can find Line faults ,
but when it all goes live , they get confused and run away , leaving Neutral to char ?

 

[gazdkw82]

i'm the opposite. iv come across more burnt line than neutral.

That being said, you've probably seen way more than me.

.... But they manage to be mostly in the line in plugs and socket outlets, or did I dream it?

That's due to dirty fuse holders ,tired -poor contact presure !
Hot live pin then takes it out on socket ( a Square black eye - I miss the round ones )
