Just bought two of these from Maplin. One I wanted for my computer and
the other I had the idea of using it for my TV. So when TV goes off,
DVD, video and STB go off as well. A pal of mine had a small house fire
from a TV left on standby.

The one for the computer works great. But I am unsure about whether to
try the other on the TV. The problem being that the master socket on the
mains panel is rated at only 5amps. The TV plug has a 13amp fuse and the
power consumption is 150watts. A 13amp fuse seems high to me but I don't
understand the relationship between power consumption and ampage.

I could just try it and see but I would like to understand it a bit more
first. Does the TV really need a 13amp fuse?

Can anyone help?

Thanks,

Steve

The TV has a static power consumption (shown on the plate) which can be
roughly converted to current (ignoring power factor) by dividing power
by 230 but there's a much larger (and unspecified) current drawn after
switch-on to degauss (demagnetise) the metalwork inside the CRT. The
degauss current may be 5-10A on the first half cycle and exponentially
decays to zero over the first few cycles. This is no worse than a CRT
monitor so if that's not popped the other mains panel you should be OK
with the TV. A 13A fuse does sound too big but you may find that the
switch-on inrush causes a smaller one to fail occasionally - suck it and
see.
