What does l and 1 mean in electrical wiring?
The incoming circuit wires that provide the power are referred to as the line wires. L1 (line 1) is a red wire and L2 (line 2) is a black wire. Together, they show the motor voltage. Having both an L1 and L2 indicate that the motor voltage may be 240 volts.
What causes high voltage in a home?
The main cause of these voltage surges in power system are due to lightning impulses and switching impulses of the system. But over voltage in the power system may also be caused by, insulation failure, arcing ground and resonance etc.
What voltage is too high for homes?
The Bottom Line. Ideally, the average voltage over a 24-hour period should be 120.0 VAC and vary between, say, 117 and 123 volts, or better between 118 and 122 volts, depending on supply and load conditions. So, the voltage should be above 120 volts about half the time and below 120 volts the other half of the time.
Can high voltage damage home appliances?
If the voltage is too low, the amperage increases, which may result in the components melting down or causing the appliance to malfunction. If the voltage is too high, this will cause appliances to run ‘too fast and too high’ which will shorten their service life.

When to contact an electrician for electrical problems?
If electrical problems are ongoing around your home, you should consider contacting a electrician. Safety around the home is paramount, so don’t leave anything to change. Get in touch with a professional, like your local Platinum Electrician, to help diagnose the problems with your home electricals for peace of mind and safety assurance.
Which is the most common cause of electrical injury?
Electrical injuries, a relatively common form of mechanical trauma, can occur as a result of lightning, low-voltage or high-voltage injury, and are often associated with a high morbidity and mortality. Almost all electrical injuries are accidental and often, preventable.
