Because of market competition, you won't go wrong most of the time if you go by price as a guide to quality when buying tools. If you're pondering whether to buy the $100 or $200 tool, go with the more expensive. Quality tools are a joy to work with and, properly adjusted, they will produce superior results. Also, it's less expensive to buy a quality tool the first time than to replace a lesser tool with a better one later on.
Never connect generators to your internal wiring. The reverse flow of electricity or “backflow” can injure an unsuspecting utility worker. For extra safety, install a transfer switch that cuts power to your home from the utility pole and switches it to your generator. Have an adequate supply of fuel for your generator and keep combustible materials like gasoline cans away from heat sources. Always fill the generator with fuel in a well-ventilated area while the generator is turned off. Never run your generator indoors or in a poorly ventilated area such as a garage. Generators, like all other engines, exhaust carbon monoxide gas, which can be deadly. Use the appropriate sized power cords to carry the electric load. Overloaded cords can overheat and cause fires. Never run generator cords under rugs or carpets where heat might build up or damage to a cord could go unnoticed.
