Main bonding and new regs?

[Carlos Arruda]

Also have a think why it is a bad idea to have a fused neutral.

What potential dangers could be introduced in to a system with a fused neutral!

Fused to what ratings would be one of them? There could only be 1A or 50A being drawn.

Potential dangers with a fused neutral? Current flows from the live conductor to the neutral, so no return path to the transform side?

I am a bit overwhelmed to say the least as my initial question derived from me thinking dual pole switch, which would make sense the question, rather than a fuse.

Ops...

Apologies to all.

Too late now for more questions. The chances are I'll post even more stupid, ridiculous questions.

Tomorrow, if work goes well, will be a better day for more questions.

Many thanks to all and good night.

Regards,
Albert


P.S: This will be stuck with me for the rest of my life. So, to a point, making a fool of myself makes things get stuck in forever. I shall never forget. Incoming neural is not and has not been fused for 60 years or more (to current date 2015). Sorry everybody.

Good follow up response, sorry if I have made you feel as if you have been stupid, not my intention, just wanting to get the basics straight.

If you have a fused neutral and that fuse blows (but not the line) then all the line and neutral conductors in the installation will rise to the supply voltage, however nothing will be working so one could assume the power is off and so safe to work on (although electricians will test for dead!).

Keep asking questions, but also think about them and how you put them across, no need to rush to post, slow and steady wins the race.

Richard;

3 years now and 3 to 4 months from finishing level 3.

My tutors wouldn't be impressed.

I should know better.

How did I took a 100A fuse (I know fuses are only in the live conductor) and thought dual pole switch is beyond me.

Did I really make this question? Can the thread be deleted? (kidding)

Anyway, much appreciated to yourself and Simons and all other that have helped in the past.

Always learning.

The forum is a great resource of information.

Albert
