[net.misc] Electrical question - some thoughts

cjy (10/20/82)

	The question of what your electrical service is can be easily
answered by your friendly electrical utility company.  You see, they
( at least in Illinois ) are responsible for your drop and will tell
you what the drop wires can handle.  ( The drop is the wiring from
the pole or distribution point to your house ) Once you know that
capacity, you can then ask a reliable electrical contractor if the
wiring in your house can be used at that current level.  If you don't
trust anyone to tell you this, you will have to determine this on your
own.

	To do this properly, you have to get a table of what wire guage
will safely carry what current.  This is found in your local wiring codes
or in the national wiring code.  ( The national code is usually much
less restrictive than local codes, so watch it! )   You then have to
determine what each circuit is wired with in your house and what you
have each circuit loaded with.  Then you can determine if you have any
excess capacity or not.

	If you have excess capacity ( the drop can supply more
current than you can use ) the simple addition of an additional fuse
box and circuit(s) is all that is needed.  If not, then you need a new
drop and then you can add additional circuits.

		I hope this helps rather than confuses,

P.S.  	I forgot to tell you that some houses are wired with main fuses
which are usually located near the point where the drop enters your
house.  The rating on those fuses ( one for each leg of the 220v. ) will
tell you the rating on the drop.  The total capacity of the house is
the sum of those fuses for 110v. usage only.  If you have any significant
usage of 220v. ( electrical range, electrical heat, large motors,
etc. ) you will have to calculate each leg separately and then remember
to add in the 220v. usage.
