mostly it's the fact that the insulation on the wires gets brittle and cracks.
and the older the wireing, the more likely it is to get "old" fast.
YES! Older homes are much more likely to have defects (such as frayed electrical wires) or suffer from fire or water leaks. You will be much safer with homeowners insurance in an older home versus a new one.
Electricity does not flow wires into your home, wires direct the flow of current into your home.
the usual cause of a SHORT CIRCUT in a home is either a diy accedent ie. a nail through a line/neutral or line/earth cable, or the old thermosetting (rubber) insulation has broke down through age and all old twin and earth should be replaced with the new grey thermoplastic twin and earth
A short circuit is a condition whereby a point or section of the circuit offer a short path for current to return to the power supply. It occurs when two or more points or sections of the circuit touches each others (but only and only if that results in drop in resistance to such an extent that it causes excessive current to flow through.
Short answer: a network is a group of computers linked by wires or wirelessly. A network can be small like a home network or very large like the internet.
There are three wires supplying power to your home two line wires @ 110 volts each and one nutral.
Primarily to keep and and all moisture away from the electrical connections. Water is a conductor of electricity ... if it comes into contact with electrical wires, it will cause a direct short and possible fire.
Open circuit breakers. Poor electrical connections to the compressor, thermostat or bad wires not telling relay to cut the compressor on. Elaborate
The standard color code for home wiring is black for hot wires and white for neutral wires.
hot wires are black, white wires are ground
Along wires. Copper wires underground or aluminium overhead.
In home wiring, hot wires are typically colored black or red, while ground wires are usually green or bare copper. In computer wiring, ground wires are typically black, while hot wires are often colored according to industry standards, such as red or yellow.
