FT2 on an electrical cord refers to the CSA (Canadian Standards Associations) test designation for wires and cables. FT2 is the minimum mandatory horizontal flame test for Flexible Cord. A burner flame is applied to a horizontal sample for five 15 second applications and must not exceed 100mm from end to end. There should also be no type of flame particles falling from the sample.
13 ft * 10 ft = 130 ft2 1 ft2 = 0.0929 m2 130 ft2 * 0.0929 m2 / ft2 = 12.08 m2
400 ft x 200 ft = 80000 ft2 80000 ft2 ÷ 43560.17 ft2/acre = 1.83654 acres
1 foot = 12 inches, so that 28/12 ft x 48/12 ft = (7/3 x 4) ft2 = 28/3 ft2 = 9.33333333 ft2 = 9 1/3 ft2
1 acre = 43560 ft2 843 acres = 36721080 ft2
12600 ft2 ÷ 43560.17 ft2/acre = 0.289255 acre
what should be the distance between instrument cable and electrical cable
Most industrialised countries manufacture electrical cable.

A device designed to permit the entry of a cable into an electrical equipment and which provides sealing and retension. Cable well tightened with supporting of cable holding material into an electrical equipment or panels.
Cable
The type of cable used for electrical service in homes, offices or commercial buildings depends on the application, load requirements and safety standards. Copper and aluminum conductors are typically the most popular choices because of their excellent electrical conductivity and durability. These cables are insulated and often covered with a sheath to protect against moisture, mechanical damage and fire hazards. A widely used option for home electrical wiring is non-metallic sheathed (NM) cable, also called Romex in some areas. It consists of two or more insulated conductors and a bare ground wire, wrapped in a protective sheath. This cable is ideal for indoor applications such as lighting, receptacles and general electrical circuits. For outdoor or underground installations, electricians often use underground feeder (UF) cable, which is moisture resistant and designed to last even when buried directly in the ground. For heavy-duty electrical applications, such as connecting the main power supply to the distribution box or powering large appliances, armored (AC) or steel wire armored (SWA) cables are used, which provide additional protection from physical damage and are suitable for both industrial and commercial applications. In some cases, service entrance (SE) cables are installed specifically to connect utility lines to a home's electrical panel to ensure a safe and reliable power supply. In modern electrical wiring systems, coaxial cables, Ethernet cables, and fiber optic cables can be considered part of the electrical service, especially in communications and smart home systems. In addition, flame-retardant and low smoke zero halogen (LSZH) cables are also in demand in high-rise buildings or hazardous areas to increase safety in an emergency.

Electrical cables carry electrical energy in the form of electricity. The energy is transmitted through the conductive materials within the cable, such as copper or aluminum wires.
An electrical conduit is a system for routing and protecting electrical wiring. A cable conduit can be found wherever electrical wiring is needed. This includes wiring in appliances or in the walls of a home.
A copper cable transports electrical signals. An optical cable transports light signals.
NM Cable
The inside metal part of a cable is usually made of copper and is where, if it is an electrical cable, the electricity is conducted.
