**How do you calculate cable size in square mm?**

Full Load Current = (KVA · 1000) / (1.732 · Voltage): Full Load Current = (100 · 1000) / (1.732 · 415) = 139 Amp….Let’s select 3.5 core 95 Sq.mm cable for single run, short circuit capacity = 8.2 KA.

- Current capacity of 95 Sq.mm cable is 200 Amp,
- Total derating current of 70 Sq.mm Cable = 200 · 0.93 = 187 Amp.

### What is 18 AWG wire used for?

18-gauge are used for low-voltage lighting and lamp cords in 10 amps. 16-gauge are used for light-duty extension cords supporting 13 amps. 14-gauge are usedfor light fixtures, lamps, lighting circuits with 15 amps.

**How many amps can 18 AWG handle?**

An 18-gauge wire can handle about 16 amps of current. It is one of the smaller wires in diameter and is commonly used for low voltage lighting.

**Is MM2 the same as mm?**

The square millimeters unit number 0.79 mm2, sq mm converts to 1 ∅ 1mm, one circle one millimeter diam.. It is the EQUAL area value of 1 circle one millimeter diam.

## What does MM2 mean in wire size?

Square Millimeters

Wire Gauge Size Chart: American Wire Gauge (AWG) to Square Millimeters (MM2) American Wire Gauge (AWG) is the U.S. standardized wire gauge system used to note the diameter of rounded, non-ferrous electrical wiring.

## How do you calculate AWG?

Here’s how you calculate AWG (American Wire Gauge) from the diameter of a wire:

- Find the ratio (R) of the wire diameter to either 0.005 inches or 0.127 mm.
- Use the equation n = -39 × log92(R) + 36 to find the AWG number.

**What is AWG in cable?**

AWG or American Wire Gauge is the US standard measure for the diameter of electrical conductors. The American Wire Gauge chart is based on the number of dies originally required to draw the copper down to the required dimensional size. It means the higher the AWG number is, the smaller the wire diameter is.
