in the USA based on buffalo ny:
there may simply be a broken or missing linking bar here.
but the answer lies under the cover panel and within the 220vac outlet.
so first with an emergency rescue crew standing by and both hands in
your pockets have your electrician measure with his multimeter set for
ac the 220 volts across the outlet in the workshop.
hot to other hot = 220.
hot to common = 110vac.
the other hot to common = 110vac.
if all true then you have 220vac working in the workshop. but since the
various desired amperages are configured by the appliance's shape and
pins of the plug, we don't know all the history here.
there are possible variations in the use of the outlet since this was
wired, including possible 110v use from the outlet with an adapter of a
device rated at only 30 amps. it may also be possible the original 220
breaker was replaced in an emergency. the wire sizes and their length
will determine the amperage. the breakers will limit the power to
protect the wires and device.
