- Electric Service


The electrical service refers to the wires that run from the steet or main pole and enter the house either underground or through the rooftop. The number of wires that enter the panel determine the voltage of the service: 2 wires = 120 volt, 3 wires = 240 volt. A home that has only a 120 volt service would be considered out of date by today's standards because larger appliances that operate at 240 volts cannot be utilized. Electrical load and demand calculations are not performed during this inspection.

40
- Main Panel


The ampacity of the system is determined by the size of the service wires, the rating of the panel and the size of the main fuse or breaker. Some older panels will have fuses while newer systems use breakers. The main disconnect is used to shut the entire electrical system in the house off in case of emergency. If no main shutoff is provided, no more than six breakers are allowed to be installed.

41
- Conductors


Conductor is the term used for the wires used for electrical installations. Copper and aluminum are common materials used for electrical wiring. The U.S. Product Consumer Safety Commision issues a booklet on the hazards of aluminum wire installations made in the early 1960's to the mid 1970's. Please obtain this information if aluminum is noted.

42
- Sub-Panel


Electrical panels that due not contain the main service wiring are called sub-panels. Sub-panels are used for a variety of of reasons ranging from house size to ease of accessibility. During inspections of homes that are occupied is is possible that a sub-panel might be hidden by pictures or furniture. Please check carefully during your final walkthrough of the house after all belongings are removed.

- Panel Notes


This section of the report notes conditions found inside the electrical panels. Repairs to wiring conditions should be performed by qualified tradespeople due to the inherent hazards.

- Wiring Notes


Our inspection of the electrical wiring and fixtures throughout the house will include random testing of outlets and lights. At least one outlet per room, all accessible outlets in the garage and on the exterior, and all outlets within six feet of sinks will be tested for grounding and polarity.
