Below is a definition from the course material. It sounds much like a legal document that doesn’t paint a clear picture of what this definition means unless you have prior knowledge.
A clear example of these types of descriptions would be very helpful to fully understanding what this and other definitions are referring too. Maybe showing and example of said device would help give a visual since all our inspections we Looking (Visually) for issues.
SEE BELOW:
Arc-Fault Circuit Interrupter AFCI is a “DEVICE” that provides protection from the effects of arc-faults by recognizing arcing and deenergizing the circuit when an arc-fault is detected.
Google AFCI.
Sounds like you need some serious education. Begin with going down to your local Home Depot / Lowes, etc. and browse all the aisles. Look-Touch-Read-Smell.
On some specific topics you are correct, that is why I am taking the course to educate myself. It was a simple suggestion that did not constitute a snarky reply that suggests that I need Serious Education!
Tomas,
Trust me, if you don’t know what an AFCI is and how it operates, going so far as to claim a simple description “doesn’t paint a clear picture”… you definitely need some serious education!!
Try this narrative.
The Arc-Fault Circuit Interrupters, or AFCI, utilize detection circuitry to discriminate between normal and unwanted arcing conditions. Once unwanted arcing condition in a circuit is detected, an AFCI breaker trips internal contacts thus de-energizing circuit voltage thus reducing the risk of potential fire to occur on combustible materials and damaging the circuit cable.
When you run into this type of thing throughout the nachi courses that you do not fully understand you just need to do additional research outside of nachi’s education courses.
Throughout all of their courses there are several issues that are not completely clear, and oftentimes incorrect, that is where additional research will be of help to you.
And you call yourself a home inspector? Arcing, when electricity jumps from a one connection to another.
Jonas, you are a constant trouble marker on the MB. I bet you personally have chased away reams of new InterNACHI members with you insults and aggressive behavior.
New members. Pay no attention to the man behind the curtain. Avoid his posts at all cost.
Thank you for that definition, I have a fairly decent understanding of electricity and the wiring in a home, I got stuck mentally on “Device” I know about GFI’s and breakers.
I am not an electrician although I have done every other aspect of construction in residential construction from Concrete Forms to roofs and everything in between.
