Back in the Philippines, it is easy to find a neighborhood handyman whenever there is an emergency electrical job that needs to be done in the house. The handyman is always available to make "house calls" when needed. You do not have to set an appointment or wait for his next available schedule to have an electrical outlet fixed or light installed. Such is not always the case here in the U.S. It is, therefore, a must for every household to have a toolbox handy for emergency purposes.
Aside from pliers, screwdrivers, and other hand tools, it is wise to keep power adaptors, extension cords, wire cutters, electrical tapes, circuit tester, fuse kits, extra light bulbs and other important electrical supplies handy at home. You will never know when you will need them.
