I just got a new microwave/convection oven. As recommended by the
manufacturer (Panasonic), it is on a dedicated 20 A circuit. I want to use
a surge protector but I cannot find one rated for 20 Amps. Can anyone tell
me where I can find a small preferrably single surge protector that is rated
for 20 A?
Check the plate rating on the oven. If it's under 15A, use an ordinary
15A surge protector.
Sometimes manufacturers recommend 20A circuits for 15A devices simply
to avoid voltage drops (expecially during fireup).
I would suspect tho that a microwave/convection oven will usually be
pretty much immune to surges.

It's not just anyone who gets a Starship Cruiser class named after them.
Microwave, like computers, contain any protection that works
at the appliance - installed internally. If anything in that
power strip surge protector was effective, it is already
inside the microwave.
Second, a power strip should have a circuit breaker. Rated
at 15 amps because that microwave power plug is a 15 amp
plug. 20 amp plugs are shaped differently so that they will
not be plugged into the standard 15 amp outlet - that is on a
20 amp breaker circuit.
Power strip surge protectors are not just grossly
overpriced. Many also forget to include that 15 amp circuit
breaker. Any power strip should include that 15 amp breaker -
that too many surge protector strips simply forget to
include. Spend excessively on a power strip surge protector -
and it does not include a 15 amp circuit breaker?
Third, all appliances have internal protection that is
effective if not overwhelmed. IOW it assumes you have
installed a 'whole house' protector with the all so critical
'less than 10 foot' connection to earth ground.
Earthing - not a plug-in protector - is surge protection. A
surge protector is only effective if it makes a connection to
surge protection. 'Whole house' protector (that cost on the
order of tens of times less per protected appliance) are so
effective. Concepts are summarized in a previous newsgroup
discussion: "Opinions on Surge Protectors?" on 7 Jul 2003 in
