It is important to say where you are doing the work when asking electrical questions on the internet. Electrical code rules are different for some states in the U.S. and different for different countries. And in Europe, electrical wiring is totally different from North America.
Some things which are allowed in the U.S. are not allowed in Canada.
In the U.S., some states use an older electrical code than others. And some states have local amendments* to the national electrical code. Here is a map which shows the versions of the national electrical codes different U.S. states use... http://www.nema.org/stds/fieldreps/N.../implement.cfm
*Ask your local electrical inspector's office where to find local amendments to the national electrical code.
