3 Rust is such an issue that can affect both operation and strength
4 HVAC
5 Rebar/steel

Music: “Just Good Ol’ Boys - Moe Bandy”

(For question #1, clearly OJ outlasts even metal roofing and slate)
(For question #3, it’s quite different residential/commercial and by climate zone).

No one got more than 3 out of 5 questions.
I was looking for paint contamination on #3, but corrosion is good also.
Everyone got the Music Question, by “Moe & Joe”.

How about you are all winners this week.
If you’d like an Inspectorsaurus Coffee Mug, PM me you mailing address.

3) What is a common issue we observe on a circuit breaker panel that may affect it’s safe operation or mechanical strength?
paint contamination

Paint contamination observed in interior of electric panel. Safety hazard, fire hazard, and maintenance concern. Paint can interfere with proper connections between electric components or proper operation of circuit breakers, creating conditions where proper grounding and electrical
connections are not present, possibly causing brown-outs, arcing, and fires.
Paint can also cause the wire insulation to deteriorate.

No approved method exists for cleaning contaminants from panel interiors or components such as bus or terminal bars, circuit breakers or fuses.
The panel and/or components inside may need replacing.

Recommend further evaluation by licensed electrician.

corrosion

Moisture that enters a circuit breaker panel can corrode electrical
wiring, connections, circuit breakers and even rust the bottom and
inside of the panel box.
Deterioration, rust, and corrosion in an electrical connection create
extra resistance to electricity flow, and consequently heat.
In severe cases, electrical arcing and excess heating can occur inside the
panel causing a fire hazard.
No approved method exists for removing/cleaning corrosion or
contaminants from panel interiors or components such as bus or
terminal bars, circuit breakers or fuses.
The panel and/or components inside may need replacing.

Perhaps our resident electrical master @rmeier2 can help out here

4) 25% to 40% of a typical building’s energy use can often be attributed to:
air infiltration
Air leakage accounts for 25 percent to 40 percent of the energy used for heating and cooling and also reduces the effectiveness of other energy-efficiency measures such as increased insulation and high-performance windows.

~~ ~~ ~~ ~~ ~~ ~~ ~~
5) ___is typically made from ___ because it has a similar coefficient of thermal expansion to that of concrete, which minimizes stress on the structure in response to changing temperatures
rebar
steel

I had trouble with that one.
The underlying code is:

NEC 230.9 Clearances on Buildings
(A) Clearances
Service conductors installed as open conductors or multiconductor cable without an overall outer jacket shall have a clearance of not less than 900 mm (3 ft) from windows that are designed to be opened, doors, porches, balconies, ladders, stairs, fire escapes, or similar locations.
Exception: Conductors run above the top level of a window shall be permitted to be less than the 900 mm (3 ft) requirement.

Option (C) read “any window”. Yet the code only applies only to “windows that are designed to be opened”. Thus (C) did not seem the correct answer, thus I chose the answer that at least did not have wrong information :-).

Exterior electrical service wires in conduit, or next to non-operable windows don’t have a spacing requirement. For operable windows sides, bottom and front is correct.

The NACHI practice question is imprecise!

I would like to donate my $50 Inspector Outlet credit to any NACHI member who would like it (if they will allow it). Just send me a message!

I would take one of those inspectorsaurus mugs though @mgoldenberg ! My wife complains that my current cup is too short and the Keurig causes the coffee to splash out and make a mess of the counter. Maybe these are taller? :thinking: :pray:
