A problem arises if the electricity supply is upgraded, by adding new generation capacity or by adding cross-connections. Because these increase the amount of power that can be supplied, all of the branch circuits must have their bus bars and circuit breakers upgraded to handle the new higher fault current limit.

Generators are rated by their electrical output, usually in watts. A minimum generator size for a small RV would be 1500 to 2000 watts. To run an RV air conditioner, a minimum of 3,000 watts is usually needed. Larger RVs with multiple air conditioners require generators with 6,000 and more watts of capacity. Generators also charge the house ...
At two multiples of the rated current, the recloser's rapid trip curve can cause a trip (off circuit) in as little as 1.5 cycles (or 30 milliseconds). During those 1.5 cycles, other separate circuits can see voltage dips or blinks until the affected circuit opens to stop the fault current.
This AFCI (the circuit breaker with the yellow label) is an older generation AFCI circuit breaker. The current (as of 2013) devices are referred to as "combination type." An arc-fault circuit interrupter ( AFCI ) or arc-fault detection device ( AFDD ) [ 1 ] is a circuit breaker that breaks the circuit when it detects the electric arcs that are ...
To prevent potential accidents caused by an unsecured wiring harness, Lucid has issued a recall for its 2022 Air EVs. To prevent potential accidents caused by an unsecured wiring harness, Lucid ...
Vehicles in overseas markets are also affected. The recall concerns a problem with the driver's side power window switch that "sticks" and could lead it to melt or catch fire. [106] It is "not something that would cause any deadly accidents like the recall of 2009" and repairs include the application of a special fluorine grease to the switch ...
General Motors is recalling nearly 900 vehicles in the U.S. and Canada with Takata air bag inflators that could explode and hurl shrapnel in a crash. The company says in documents posted Tuesday ...
The automaker began investigating and hasn't determined an exact cause. But preliminary information points to a manufacturing problem from Feb. 22, 2014 to March 7, 2014, the documents said.
