My main concern with using a powerboard, because I don't have any
choice, was using the homeplug device with other devices overloading the
powerboard having had issues with a 2000W heater destroying powerboards,
and having the electronic store that provided the powerboard tell me I
should never plug the heater into the powerboard, that I should only
ever plug it into the wall power socket as powerboards are not designed
for that load.
Rick Stevens:
Yeah, probably way too much juice to pump through the powerboard. 2000W
heaters draw, what, 11.8 amps at 120VAC (5.9A at 240VAC)--probably with
a pretty nasty power-on spike. That's quite a bit to be asking of a
circuit board and plastic.
But how is that any different from the wall socket? Any powerboard that
cannot handle the full load that could be plugged into a wall socket
shouldn't be sold.
Completely different certifications, construction and materials. Wall
sockets have to be certified by UL and several government agencies (at
least in the USA). Devices that plug into outlets only have to meet
what they're labeled as supporting (and often don't even do that). Take
a careful look at the VA (wattage) rating of an extension cord or outlet
strip. Often they don't support the full wall socket rating. In the USA,
that's about 1800VA or 1270W (120VAC, 15A) and the same is probably true
of a lot of powerboard units.
