Electrical wiring should always be installed by a licensed electrician and inspected by your local wiring inspector. Your house or apartment may be inadequately wired if: Lights dim and motors slow down when an appliance goes on; Fuses blow or circuit breakers trip frequently; Toasters or irons fail to heat properly; The television picture shrinks.
Shavings can pile up around a hole being drilled, making it hard for you to see what you are doing. To prevent this, push the point of the drill bit through a 4-in. strip of masking tape, then draw the tape up the bit so it will clear the work. Fold the strip lengthwise to bring the sticky sides together. The tape “wings” will act as a fan to clear the surface.
