subject to your local requirements: unless its installation manual
advises otherwise: it should have its own separate circuit and wire
from the fusebox. it is not likely that there is an unused circuit
waiting for you in the old fusebox, especially since the disposal
required a similar circuit. however, if you are using a gas stove, look
over the main electrical panel and determine if the electrical RANGE
circuit is unused. your electrician will advise you if with its 220v
pair of cartridge fuses it could feed a new circuit breaker subpanel.
make sure you get enough extra circuits and spare breakers for the next
guy. your electrician will prefer to update your home service, and you
may want that for central air or other modernization. this will allow
modern features to be chosen on your new circuit breakers as well.
