which circuit breaker? either engine compartment or r.h. dashboard panel
There is no current in a 60A circuit breaker. The above circuit breaker is a 2 pole circuit breaker that will trip when more than 60 AMPS is being drawn through either of the 2 poles.
Assuming the circuit breaker is good, you have either an open neutral or an open hot wire leading to your lighting circuit.
A trip free circuit breaker is one that will disconnect a circuit even if the manual switch is held at the "on" position. It is a safety feature to prevent a circuit breaker being disabled either deliberately or accidentally.
A circuit breaker does not "cause" smoke. A circuit breaker "breaks" a circuit when there is too much current, creating a hazardous condition for the wires that are connected to the circuit breaker. The circuit breaker PROTECTS you from electrical fire. Find the source of the smoke; what burned? If a circuit breaker tripped during the incident, it is usually caused by melting/burning wire insulation, either inside or outside of an appliance. If the insulation inside the walls of your house has burned/melted, it could be that the circuit breaker was too large for the wire or that the circuit breaker failed to shut off at the appropriate current load. If the circuit breaker failed, your insurance should help you. If an appliance overloaded the circuit, your insurance should help you. If someone connected an oversized circuit breaker, causing the wire to overheat, your insurance company may refuse to help you.
A 240 Volt circuit breaker uses an interlock to shut down BOTH sides of a breaker when either experiences an overload condition. The interlock is essential to prevent electrocution and damage to electrical equipment.
The device used to protect and open (break) a circuit under a fault condition, would be either a fuse or a circuit breaker.
A circuit breaker is an overcurrent protection device. It is designed to interrupt a circuit in the event of either an overload current (due to too heavy a load) or a short-circuit fault (direct line-to-neutral or line-to-earth fault).
generally, an electric range will use either a 30A circuit or a 40A circuit. Check the requirements of the range.
Either a fuse or a circuit breaker.
If the circuit breaker to a dryer, or to any load, keeps getting hot and trips the breaker, then either the load is pulling too much current or there is a loose connection in the breaker or breaker panel. Either condition must be fixed to reduce the risk of fire.
If there is a current in excess of rated breaker current and breaker doesn't trip, either the breaker is faulty or the current was transient and very quick and the breaker didn't react.
