What are reasons for arcing at the commutator?

A shorted coil or shorted coils in the rotor will cause arcing at the commutator. It should also be noted that if the brushes are damaged badly enough where they make contact with the commutator, this can cause arcing. Oh, and let's not forget that a stuck brush or brush spring will prevent a brush from making proper contact with the commutator. Arcing can result from that, too.

What could be the cause of arcing between the buss bar and a breaker?

Arcing is caused by a poor electrical connection. The breaker is not making good contact with the buss bar. Try replacing the breaker.


What are arcing contacts?

Whenever an electrical contact is made or broken, an electrical spark jumps through the air between the two contact points while they are very close together but not yet, or not any longer, touching. That spark jumping is an electrical arc and the event is arcing contact. The main cause of arcing is the property of a circuit to maintain the continuity of the current, so whenever the contacts separate to break the circuit the air (or any dielectric medium that is used) ionises and continuity of the current is maintained, at least momentarily.


Do divergent boundaries cause island arcing?

No. Divergent boundaries cause mid ocean ridges (MORs) to form.


Can loose notted wires cause fires?

Loose wires can cause fires by arcing or sparks flying into combustible material. I don't know about the "notted" aspect unless it is a typo and means ROTTED. In that case, yes rotted wires can also cause arcing or sparks too.


Do electrical plugs cause sparks that start fires?

they can because bad contacts can cause arcing which can ignite combustible material near by.


Will a loose kill switch wire on a out board motor cause bogging down?

A loose kill switch wire on your out board motor will cause the engine to lose power. As the kill switch loses contact the motor will begin to bog down or completely quit.
