The two types of circuit protectors found in homes today are fuses and circuit breakers. Fuses are found mostly in older homes or for specific equipment installations. They are normally not desirable for your main panel box because normal replacement will require you to expose yourself to a potential electrical accident. Many old fuse boxes contain oversized fuses and in poor distribution for modern electrical requirements. Most homes today have a minimum 100 Ampere power supply with 110/220 voltage capability or greater. Some circuit breaker types are prone to over heating and malfunction. Your inspector will not normally turn breakers on and off or remove fuses because the failure of such devices could affect the current homeowner or the dwelling. He will however advise you in great detail about the current condition of these devices and possible repairs required.
