I am unaware that there is an average residential wiring job. Mainly, there is no average residence.
Codes will help determine the minimum amount required, but one can easily exceed this amount.
And that is my current answer.
And just so we know what's watt-
The watt (symbol: W ) is a derived unit of power in the International System of Units (SI). It measures rate of energy conversion. One watt is equivalent to 1 joule (J) of energy per second .
In terms of mechanical energy, one watt is the rate at which work is done when an object is moved at a speed of one meter per second against a force of one newton .
1W = 1J s-1 = 1kg m2 s-3 = 1N m s-1
By the definitions of electric potential (volt ) and current (ampere ), work is done at a rate of one watt when one ampere flows through a potential difference of one volt.[ 1]
1W = 1 V × 1 A
