When fuse boxes were in widespread use, most homes had only 30 or 60-ampere service. Today’s homes need at least 100-ampere service to safely supply power for major appliances. If you have a fuse box and you’ve added any large appliances over the years, We recommend that you have your home wiring inspected to make sure it is still safe.
There’s an important difference between a fuse panel and breaker panel. Both devices are designed to trip (turn off) in the event of an electrical overload, i.e. 20 amps of electrical load on a 15 amp circuit would cause a trip. But a breaker is mechanical and may be reset. A fuse, however, is one time only and must be replaced. Note that modern breakers are much more efficient and offer greater levels of protection.
An intermittent chirp is probably an indication of a defective smoke detector.
A consistent chirp is probably an indication of a low battery condition, and the smoke detector requires a new battery.
GFCI stands for Ground Fault Circuit Interrupter. In layman’s terms, this device protects you from electrical shock. When it senses the slightest increase in resistance resulting from ground fault, (i.e., the use of electrical devices in or near water), it trips off to protect you.
The black button is a test button and when pressed, it should deactivate the outlet and any other outlet fed from it – indicating a properly functioning device.
The red button is the reset button that you depress to reactivate the outlet or outlets in the event of deactivation resulting from a fault.
Use of non-brand name bulbs.
Larger wattage bulbs, which cause excessive, heat build-up shorting the life of the bulb.
