Esteemed colleagues,
Here in North America a domestic or commercial multi-outlet
power strip would be cord connected thru a duplex outlet protected by a 15A
(or sometimes 20A) circuit breaker. The max load allowed in the circuit by
the US NEC would be (80% of 15A) 12A for the total load (or 80% of 20A) 16A
on the 20A breaker. Note that the US NEC requires that any device plugged
into a duplex outlet must not use the full load capacity of the circuit -
20% must be left for the other outlet's load.
Trying to understand the loading basis for a Euro power
strip. Is the usual protection a 10A breaker? And would the power strip be
rated and evaluated at that load level? What other considerations come into
play here?
How about a UK power strip. The usual protection is the
13A fuse in the power plug (altho smaller values seemed to be used also).
Would the power strip be rated and evaluated at that load level? What other
considerations come into play here.
For a Japanese power strip what is the normal breaker
protection for the installed circuit? What would be the max rated load for
the power strip? What other considerations come into play here also?
Looking forward to your replies on this issue.
