The idea of working on electrical projects may give you some minor feeling of panic, but many typical household dilemmas are simple to repair as long as you obey the rules of currents and always follow safety guidelines. Every person in your household who is old enough should know how to turn off and restore your home’s power supply in case of power failure or to make electrical repairs. It will seem obvious to state that you should never work on anything electrical that is conductive, or live, without first disabling it, but let’s face it, even the best of us get lazy once in awhile.
Few people realize that it is necessary to disable the power supply before you drill into ceilings or walls—you may hit a wire without knowing it, so shut off power at your circuit box before you drill. Keep a flashlight near your breaker box so you can see what you’re doing. Older homes tend to have fuse boxes, while newer or refurbished ones have circuit breakers, but they serve the same function. If you have a fuse box, keep the appropriate fuses on hand and never use fuses that are too powerful for your fuse box. The amp ratings should be clearly marked inside the box door.

Iowa is bordered on two sides by rivers; the Mississippi separates it on the east from Wisconsin and Illinois, and the Missouri and the Big Sioux separate it on the west from Nebraska and South Dakota. The state is bounded on the north by Minnesota and on the south by Missouri. Iowa is an area of rich, rolling plains, interrupted by many rivers. The terrain is low and gently sloping, except for the hills in the unglaciated area of NE Iowa, the steeply sloping bluffs on the banks of the Mississippi, and the moundlike bluffs on the banks of the Missouri. The rivers of the eastern two thirds of Iowa flow to the Mississippi; those of the west flow to the Missouri. The original woodlands, which included black walnut and hickory, were destroyed by lumbering and land clearing in the 19th cent., and present wooded sections are covered only with second or third growths of timber. Only 0.1% of Iowa, the lowest total in the 50 states, is owned by the federal government.
