The nameplate of a hermetic refrigerant motor-compressor that is designed to operate continuously at currents greater than 156% of the rated-load current is marked with branch-circuit selection current.
<h3>What is a hermetic
refrigerant motor-compressor?</h3>
A hermetic refrigerant motor-compressor can be defined as a mechanical device that is designed and developed by combining a compressor and motor in a single outer-welded steel shell.
Basically, a hermetic refrigerant motor-compressor is used in the following areas:
- Small refrigeration equipment.
According to HSE, the nameplate of a hermetic refrigerant motor-compressor that is designed to operate continuously at currents greater than 156% of the rated-load current is marked with branch-circuit selection current, so as to ensure safety for end users and technicians.

Answer:
the true stress for the second material is 629.19MPa
Explanation:
given for material 1,
l₀ = 48mm
l₁ = 53.5m
e = change in length = 53.5 - 48 = 5.5mm
true stress = 368MPa
strain = Δlength/original length = e/l₀
stress = force / area = F/A
young modulus, E = stress/strain = Fl₀/Ae
E = stress * l₀/e
E = 368 * 48/5.5 = 368 * 8.73 = 3212.64
for material 2 of the same properties, meaning E for both material is the same, therefore,
l₀ =48, l₁=57.4, e = 57.4-48
e=9.4mm
E = stress * l₀/e
3212.64 = stress * (48/9.4)
3212.64 = 5.106 * stress
stress for 3212.64/5.106 = 629.189MPa
the true stress for the second material is 629.19MPa
Control systems govern the behavior of dynamic systems, while electronic systems are the ones that package the tiny components needed to conduct electricity. Thus, option E is correct.
<h3>What exactly are thematic groups?</h3>
Thematic groups are made up of individuals who focus on the same theme or idea. Thematic teams working on various initiatives and concepts are made up of individuals with experience in various systems.
- The function of the control system has been to regulate dynamic systems in order to bring about the desired result.
- The function of the electronic system thematic group is to package electronic miniatures in systems that play the job of directing electricity. Thus, option E is correct.

Answer:
Sense the current leakage
Trip the circuit
Cut off the electricity
Explanation:
The correct order is -
Sense the current leakage
Trip the circuit
Cut off the electricity
Reason -
First step has to be taken to sense the electric current leakage without it being detected, it cant be dealt with.
The second step consists of tripping the circuit so at to remove the flow of electricity.
The third step is to Cut the electricity off so to stop the leakage and be safe.
