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.

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.

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
