While wiring a light switch or a oulet may be relativly low risk, doing home electric repairs and installations is very dangerous, serious injury or death may result from attempting electrical projects.
 
 
In most cases its best to leave it to the professionals. State, city and county building codes vary widely before any home electric repairs or upgrades are made be sure to check with your local city hall to see if permits have to be pulled or any other restrictions that might be applicable.
 
 
Important!!! Before starting any electric project double check that you have the electric shut off.
 
 
If you have a question about a repair post it in the user feedback.
