The part that cracks on a spark plug is the insulating material that shields the metal part of the plug that conducts the electrical spark, potentially allowing it to escape or leak and possibly ignite any flammable substances or materials as it grounds itself.
The cracked plug can cause the wires to spark and cause a fire. When the wires are plugged into it where the crack is the wires can touch the socket and cause the fire.
because it can cause a fire
An outlet will only get hot enough to cause a fire if:There is a problem with the wiring connecting it to the supply, this will become quickly obvious when in use.It is overloaded. The electrical supply is supposed to have a fuse or breaker to prevent this.There is also a 3rd cause of potential fire:3. A loose wall socket connectionLoose wall socket connections can be a MAJOR concern, causing the plug and socket to overheat. This is primarily a problem on older homes.
First thing to check is the fuel pump relay. IT could also be that big air clearner hose. If that is broken or cracked anywhere these it will cause over fuelling.
Depending on what year the vehicle, if the vehicle year is pre-cat it could cause a back fire under deacceleration. If the vehicle year is post-cat it could cause false 02 readings.
It would if the battery voltage was lowered enough to cause it not to fire.
It depends on the cause of the furnace fire. Remember that homeowners insurance is all tied to the cause and whether or not it is a covered cause. If the furnace fire was caused because of lack of maintenance then it would not be covered. If the furnace fire started because of some other accidental covered cause then it would be covered.
This is normally a sign of a loose connection or fault. Its really important you have a qualified person check it out as it can cause fire or electric shock.
Too much current = cables heating, may cause fire. WHICH ALSO MEANS, BRAD IS FAT
Appliances means power demand in a home USA 15 amps is the maximum power can be safely drawn from a wire circuit. IF more then that is required from a socket then wiring and the socket will be subject to heating probably melting the insulation and cause a fire.

it will cause fire
