US socket distribution blocks

not realy to do with it being AC or DC, the fault is before wether live - earth or live neutral, the overload will occer at that point, the current increase will be in the conductors before and up to that point, not after.

 

If Ac does not flow in any one diection, go grab the live and then the neutral in a bared wire, let me know wich hurts. Obviously dont do that, but i think youll see my point.

 

But isn't it strange that rest of the world get by without an additional fuse to protect the cable?
Anything to do with the ring main system? Is this only used in the UK?

 

No idea on regs in other countries.
UK regs (is it european now?) say that the plug must be fused irrelevant of the type of circuit, ring or radial.

 

With AC you are likely to get thrown off as the current ALTERNATES. Shock from DC is therefore much more dangerous.
If you don't believe me, go grab the live and then the neutral in a bared wire, with AC. Then do the same with a high enough DC voltage.
Let me know which hurts you more

 

Ive had 380DC and 240AC belts. You get use to it after a while. Wasnt to keen on the 415 belt tho.
I think youll find it is the other way round, AC will contract muscles causing you to grip, DC will have the oposite effect, hence a shock from something like an auto ignition is called a wrist snapper.

 

No. UK regs are not European now. They still fit 2-pin unfused plugs.
I was thinking freely in terms of electricity not regulations. May be UK electricity is much more than dangerous than electricity in Europe and the US I blame it on the weather

 

I guess your footware helped reduce the current flow.

 

in respect of?
If you mean the DC, doubtful as i have one hand in the supply box and the other on an ally step ladder.

 

Next time, make sure that your ally ladder do not have non-ferrous feet.
To be on the 'safe side' and make sure of a good current flow. Hook up a cable (unfused) between the supply box and your ally ladder. This 'tweak' should improve your experience with AC or DC.

 

non-ferrous??

 

Gold plated OFC?

 

ok
why?

 

Just for once I'd, perhaps naively, say that I think we're doing it better. If there is a fault in a cable this is the sort of thing that could easily cause a house fire so having a fuse to reduce the chance of that seems an eminently sensible idea to me.

 

Common understanding

That is the reasoning. I have 2.5mm T&E as the cable between the wall and the equipment. I have also modern circuit breakers and they are faster reacting than fuses. It's possible that if you hifi is on a line with 30A fises then a lower rated fuse is safer in the plug. My system is on 2 x 16A lines, without plug fuses.
