* Heat generation due to vibrations and poorly tightened coupling screws which result in overheating is the most frequent cause
to fire in outlets. At low twisting moment are achieved temperatures up to 900c
in the screw clamp. When the connector was moved forwards and backwards are
achieved temperature, up to 300oc. Thus it is great danger for
ignition and fire in out let. The fire hazard increases in a poorly screwed
clamp connection.
* Low voltage: This is an electric
engineering term that broadly identifies safety consideration of an electricity
supply system based on the voltage used. The most commonly used ones include
“Mains Voltage” 230V AC. Low Voltage” is characterized by carrying a
substantial risk of electric shock, but only a minor risk of electric are
through air. Low current is distinguished from “ Extra low Voltage, which
carries a much reduced risk of electric shock. But high Voltage is where
electrical arcing is a substantial additional risk
* In an improper installation, the over current
from a short circuit may cause ohmic heating of the circuit parts with poor
conductivity (faulty joints in wiring, faulty contacts in power sockets, or
even the site of the short circuit itself). Such overheating is a common causes
of fire.
