200 amp service is the current standard for new homes and updated service panels.
Standard electrical cable sizes.
The gauge and diameter of the wire are inversely related.

In large homes 250 amp or larger service capacity may be needed particularly if the home has electric heating.
The ratio of these diameters is 1 92 and there are 40 gauge sizes from no 36 to no 0000 or 39 steps.

British standard wire gauge is a set of wire sizes given by bs 3737 1964 now withdrawn and is generally abbreviated to swg.
It can supply all standard electrical needs in a typical family home buy may not support a large electric heating system.
The electrical calc elite is designed to solve many of your common code based electrical calculations like wire sizes voltage drop conduit sizing etc.
Lengths of wire vary from standard cuts of 50 100 250 500 and 1 000 feet but can be special ordered for specific lengths.
Electrical wiring is rated in gauge for its size and amp rating.
It is also known as.
The electric toolkit provides some basic electrical calculations wiring diagrams similar to those found on this website and other electrical reference data.
Among other things it defines a set of standard wire cross sections.
In other words as the gauge number gets higher the diameter of the wire gets smaller.
Imperial wire gauge or british standard gauge use of swg sizes has fallen greatly in popularity but is still used as a measure of thickness in guitar strings and some electrical wire.
In the wire size table below give the typical diameter of 14 copper wire as 2 05 to 2 32 mm or about 0 081 0 092 inches.
These are mostly used for appliances and objects that require much more electrical power to operate or special use situations.
The most common gauges are 10 12 or 14.
Aside form the 3 most commonly used cable sizes of 1 1 5 and 2 5mm twin and earth there are in fact several other larger sizes of cable that include 4mm 6mm 10mm and 16mm.
The wire gauge indicates the electrical wire sizing as defined by the american wire awg system.
Increasing awg give decreasing cross sectional areas the smallest awg size being 50 and the largest 0000.
Because each successive gauge number increases cross sectional area by a constant multiple diameters vary geometrically.
By definition no 36 awg is 0 005 inches in diameter and no 0000 is 0 46 inches in diameter.
