Extending branch circuits off of ungrounded systems, 2 wire system no equipment ground.Chelan Home Inspections Dealing with older wiring systems can be a bit tricky for new homeowners and those who live in these older homes. Often in older homes (Pre-early 1960’s), we have ungrounded wiring systems and often fewer receptacles than what we are used to in more modern homes (What is a Sufficient Number of Receptacles? A historical review). So how do we deal with this? What can I and what can’t I do to add new receptacles and extend branch circuits? So the question came up can you extend … (6 comments)
I use the “Seatbelt” analogy when it comes to how look at the home's nervous system… your electrical system.
The analogy goes- “We all wear seatbelts but how often do we really need them? Less than 95-99% of the time, but we want them there when things goes wrong.”
I know this for a fact when I got t-boned by a pickup truck, was hit sideways, hit the curb and proceeded to pull a TV stunt ride on two wheels across the road and smacked … (9 comments)

Color Matters- Electrical Wiring Wenatchee and Cle Elum Home InspectionOne thing I find on home inspections is that wires are not properly identified. This can be a safety hazard because colors in wiring carry a certain designation. If a conductor is missed colored it could be mistaken for a hot conductor when it is a neutral or more important a neutral (grounded conductor) when it really is a hot conductor. The NEC (National Electrical Code) requires that white or grey be used for the neutral power conductor (grounded conductor) and bare copper, green, or green with yellow stripe for the protective ground … (7 comments)

Grounding to Water Pipes- Electrical Inspections- Wenatchee and Quincy Home InspectionsWhen performing a home inspection and evaluating the electrical system I am always trying to confirm if a grounding system is proper. The Washington State Home Inspector Standards of Practice states (WAC 308-408C-110 Electrical system.)-A home Inspector must:(b) Report (i) The existence of a connected service-grounding conductor and service-grounding electrode when same can be determined. (ii) When no connection to a service grounding electrode can be confirmed.The purpose of the grounding electrode is to be connected to earth and to the electrical equipment so it establishes a zero difference of potential … (28 comments)
electrical inspections: When Systems Age, Electrical Systems

When Systems Age, Electrical Systems- Chelan and Leavenworth Home Inspection Services.As home inspectors we are always evaluating major systems of a home. It is pretty common for a home inspector to state a hot water tank is at the end of it life, or a roof, HVAC etc…It seems pretty clear to everyone for these systems because we are used to the notion that these systems wear out and need replacement.But one major system that does not come up in this conversation as often and should is the electrical system. This includes the service panel, overcurrent devices and any associated wiring … (7 comments)
