5.2. PROTECTION AND SIGNIFICANT CAUTION
All live wires or parts are electrically isolated
from the earth. However, there is an additional
safety feature, which composes of all accessible
conducting parts being connected to an earth wire
so that these parts cannot become hazardous
if the main isolating system fails.
