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.

Nebraska is roughly rectangular, except in the northeast and the east where the border is formed by the irregular course of the Missouri River and in the southwest where the state of Colorado cuts out a squared corner. The land rises more or less gradually from 840 ft (256 m) in the east to 5,300 ft (1,615 m) in the west. The great but shallow Platte River, formed in W Nebraska by the junction of the North Platte and the South Platte, flows across the state from west to east to join the Missouri S of Omaha. The Platte and the Missouri, together with their tributaries, give Nebraska all-important water sources that are essential to farming in this agrarian state. Underground water sources are also widely used for irrigation. The river valleys have long provided routes westward, and today the transcontinental railroads and highways follow the valleys.
