Just further proof you are clueless. A 10A circuit describe the actual circuit funnily enough. You know from breaker to outlet.. It's rated at 10A and is a circuit that ideally is expected to put a maximum of one device with a max rating of 10A on. Of course there aren't many appliances which draw this so we take an avg measurement of what a typical current draw is for a device and allow that many outlets on the one circuit for home use.
However once we move on to industrial use (well in the home) 15A outlets can only have one GPO connected. End of story.
Absolutely fucking positively clueless you are...Even a tradie understands that much so I can only surmise you aren't even that.

The reason a power circuit has more than a 10a protective device is because more than one appliance may be used at one time.

It has it because there is always a bit of leeway in spikes etc that can occur and you do not wish to trip it. That is why it's more than 10A, usually 15a for a 10A circuit and the outlets are usually at least 15A rated internally if not 20A usually at least.
It's bloody simple. The reason why you have 10A rated switches is because the circuit is rated for 10A technically as its operational load. Anything more and you are overloading it from a purely spec related manner for it's intended usage.

Utter and COMPLETE RUBBISH (with a qualifier). If you had any clue you would understand that a 15A circuit (protected by a 20A fuse) runs on exactly the SAME wire gauge as a 10A circuite (protected by a 15A fuse). You don't place a 20A fuse on a 10A circuit despite the same guage of wire used for both in most home installations. Anyone who does is asking for trouble since most gpo design for 10A circuits assumes a 15A breaker. Infact if your insurance company found out and you had a fire and you put a 20A fuse on a 10A circuit your insurance would be null and void.
In a perfect world (and here is the qualifier) we would put a 20A fuse on a 10A circuit because the wire used is the same for both and is capable of carrying that much however in the real world where the "system" is designed we put a 15A fuse on it for a 10A circuit. We aren't as braindamaged as you to JUST look at the wire and say it can do X amps therefore we put X amp circuit breaker on it.
Anyway I've wasted enough time with amatuers and am over arguing with people who really don't have much of a clue. Go and do a course and understand what you are talking about and why things are done rather than passing down second hand knowledge of what you heard from a mate who heard etc..It's becoming quite a joke.
