If I was running a 10A plus load for Hours, a 16A BS4343 (Commando) socket would be my socket of choice.

 

Noting of course that BS 7671 prohibits those in domestic premises, because they are not shuttered.

 

553.1.201 Every socket-outlet for household and similar use shall be of the shuttered type and, for an AC installation, shall preferably be of a type complying with BS 1363.

 

If the 13 Amp plug is likely to overheat could I not apply 553.1.5 (iii) and use a caravan socket and plug?


Z.

How do you work that out? (iii) applies to a plug and socket-outlet "not complying with BS 1363, BS 546 or BS EN 60309-2"


And regardless, 553.1.201 is not a requirement for a BS 1363 socket-outlets to be used exclusively in household and similar use, it's just a preference, but for all socket-outlets for household and similar use to be shuttered.


I have a 16 A BS EN 60309-2 socket-outlet in my detached garage, but I've taken a decision it's not "household and similar use" because it's for my welder which specifically states it can't be used with a BS 1363-1 plug.


However, I'm sure there will be people who disagree with my decision and will say that the garage is part of the household ...

Would that rule out the use of a B.S.4343 socket or plug?

Definitely. It's not shuttered. Reg 553.1.201 still applies.


BS 4343 was completely withdrawn in 1997 and replaced by ... BS EN 60309-2: https://shop.bsigroup.com/ProductDetail?pid=000000000000372843


The standard continued to carry the BS 4343 number after BS EN 60309-2 until 1998: https://shop.bsigroup.com/ProductDetail/?pid=000000000000281586


So, it's one in the same thing ... if you can't use BS EN 60309-2 socket-outlets, you can't use BS 4343 ones.


And BS EN 60309-1 (non-standard) and BS EN 60309-4 (interlocked switched) won't help with compliance with BS 7671. because again they are not shuttered and Reg 553.1.201 still applies.


THe only option for a non-shuttered socket-outlet, in my view, is one with an electrically or mechanically interlocked isolator, so the power is effectively isolated whenever the plug is removed. But this would have to be declared as a departure with 553.1.201 ... or you make the decision that a detached garage with operations going on that require industrial socket-outlets are by definition not "household and similar use".


Difficult to determine an EV charging station is not "household and similar" especially when the EV charging standard requires domestic chargers to have shuttered sockets, or electrical/mechanical interlock in the way I've described.
