To determine the annual accretion, find the difference between the cost of the bond and par value; divide the result by the original number of years to maturity. The following question tests your understanding of accretion. Mr. Dancer purchases a 5-percent corporate bond with 10 years to maturity at 80.
Look for horsepower (HP) ratings to compare the lifting power between garage door opener models. Ratings ranging from 1/2-horsepower to 1-1/2 horsepower are typical for residential models. If you have a sectional double-car garage door, a 1/2-horsepower motor should be sufficient, but a higher-power model will operate with less effort and less wear and tear on the motor.
The breaker size depends on the type of garage door opener you have and how many you have. If you have a 1 car garage, a 15 Amp circuit is more than adequate. If you have a 3 car garage with three openers you may want to consider a 20 Amp circuit breaker. Here are the details: Most modern garage door openers draw from 3 to 5 amps, depending on what type of lighting your opener has. If your opener has a 200 Watt lighting system, for example, the lights alone will draw just under 2 Amps. Amps x Volts = Watts. Thus, Watts / Volts = Amps.
