220v Main Breaker Switch

NBT1-63 series small air switch has skillfully set the threshold of closing force of the operating handle in the products with higher rated current level (50a and above). Only when the operating force reaches a certain value, In order to make the contact close and make the contact close at a certain high speed, the influence of human factors on the contact closing speed is relatively eliminated, the electric wear loss of the contact is reduced, and the service life and reliability of the circuit breaker are improved. The comprehensive effect of NBT1-63 series small air switch is characterized by good current limiting characteristic, short arcing time, long service life and reliable performance.

FAQ

Q1: Can water in a breaker box cause a fire?

A1: The increased resistance in the circuit that corroded terminals and connections can cause produces heat, which may eventually ignite a fire. Water getting inside the panel box can also cause circuit breakers to malfunction. Although the damage may not be visible, opening the panel box yourself could be dangerous.

Q2: How do you fix an overloaded breaker?

A2: Solutions to Overloads. The immediate solution to an overload is simple: Shift some plug-in devices from the overloaded circuit to another general-purpose circuit. Then flip the circuit breaker back on or replace the fuse and turn stuff back on.

Q3: How do you split the load on a breaker?

A3: If you split a single circuit breaker into two and run them in parallel with each other then the breaker pair *SHOULD* allow twice as much current into that portion of the circuit without tripping.

Q4: Can you overload a breaker panel?

A4: Make sure you do not overload your service panel. A panel's total amperage is printed near or on the main circuit breaker, which controls all the circuits in the panel. For example a 100-amp service panel may have circuit breakers that add up to more than 200 amps. This is normal.

Q5: What happens when a breaker is overloaded?

A5: Exceeding the rated load for the circuit wiring causes the circuit breaker to trip, shutting off the power to the entire circuit. If there were no breaker in the circuit, an overload would cause the circuit wiring to overheat, which could melt the wire insulation and lead to a fire.
