Wires and Cables
Wires are those conductors 3.26mm or No.8AWG and smaller in sizes.
Cables on the other hand, are those which are larger than the wires. So, wires are
small cable while cables are big wires. Wires and cables are either stranded or solid.
Stranded wire- contains a group of wires twisted to form a metallic string.
Solid wire- consists only of single conductor.

Note: If you want to know the equivalent size of wire using the conversion table, the #
8 AWG is equal to 3.263mm or 3.2mm the actual commercial size, the # 10 AWG is
equal to 2.590mm or 2.6mm the actual commercial size; the #12 AWG is equal to
2.052 mm or 2.00mm; and the # 14 AWG is equal to 1.628mm or 1.6mm. Generally,
wires and cables available in the market are even numbers in American Wire Gauge.
Ampacity is also called current-carrying capacity, this is the maximum current, in
amperes, that a conductor can carry continuously under the conditions of use without
exceeding its temperature rating.
In Philippine Electrical Code (PEC), Conductors size and rating shall have sufficient
ampacity to carry the load. They shall have adequate mechanical strength and shall
not be less than the rating of the branch circuit and not less than the maximum load
to be served.

(3.5mm² or 2.0mm) and current does not exceed 20 ampere. For lighting circuit where
load is incandescent bulb and fluorescent bulb the standard size of wire should be #14
AWG (2.0mm² or 1.6mm) where current should not exceed 15 amperes. For heating
appliances such as electric stove and motorized load such as freezer, refrigerator,
washing machine, and air-conditioning unit the size of wire shall be #10 AWG ( 5.5mm²
or 2.6mm), however, heating appliance and motorized load should be in separate
circuit. Lastly, the standard size of wire for service entrance is #8 AWG ( 8.0mm² or
3.2mm ) with 40 ampere for TW and 45 ampere for THW/THWN.
Conductor Material
One of the factors that determines the resistivity of wire is the material from
which the wire is made. The table indicates that a copper conductor is permitted to
carry more current than an aluminum conductor of the same size and insulation type.
An 8.0 mm2 copper conductor with Type TW insulation is rated to carry a maximum
of 40 amperes. An 8.0 mm2 aluminum conductor with Type TW insulation is rated to
carry only 30 amperes.
Another factor that determines the amount of current a conductor is permitted
to carry is the type of insulation used. This is because different types of insulation can
withstand more heat than others. The wire table is divided into columns that list the
trade name: identification letters, maximum operating temperature, whether the
insulation can be used in a wet, damp, or dry location, material, thickness, and outer
covering. A good thing to remember is that insulation materials that contain the letter
W, such as RHW, THW, THWN, and so on may be used in wet locations. A conductor
which has an insulation material that contain dual H(HH) letters can withstand higher
temperature.
In the Table below, the first column on the left side is the size of wire in mm²
from 2.0 down to 500. On the last column (right side) is also sizes of wire in AWG
from #14 AWG down to 1000. The 2nd
, 3rd
4th
and 5th
column from left side is the
ampacity of copper wire, the unit is Ampere. The 6th
, 7th
, 8th
, and 9th
column is also
the ampacity of Aluminum wire.
15. 14
How to read the table above in determining the ampacity of wire.
Example:
Problem 1: What is the ampacity of 5.5mm² copper wire, type THW?
Answer: 30 Ampere
1. Look for the column of the types of wire (FEPW, RH, RHW, THW, THWN,
XHHN, USE, ZW) such as the circled above (left side)
2. Locate the size of wire on the first column, in this case 5.5 mm2 is encircled
3. Look for the number/answer where the types of wire (THW) and the size of
wire (5.5) intersect, thus, the answer is 30 Ampere.
Problem 2: What is the ampacity of 6 AWG aluminum wire, type THHN?
Answer: 55 Ampere
1. Look for the column of the types of wire (TBS, SIS, FEP, FEPB, RHH, THHN,
THHW, XHHW) such as the circled above (right side)
2. Locate the size of wire on the first column, in this case # 6 AWG is encircled
3. Look for the number/answer where the types of wire (THHN) and the size of
wire (6) intersect, thus, the answer is 55 Ampere.
If the size of wire is unknown and the given is the type of wire and ampacity, look at
the big arrow.
Example:
Given:
Type of wire = THHN, 90 ⁰C
Ampacity = 90 Ampere
Size of wire = ?
