In Australia, when it comes to home decoration, we often have doubts about purchasing wires and cables. We often hear about tps1.5mm square, tps2.5mm square, 4mm square, 6mm 2c e tps, 10mm tps cable. So what does "mm ²" mean about wires and cables? What does it mean? How many mm ² electrical TPS cables should be selected for home decoration? Below, the editor will provide a detailed introduction for everyone.
1, What does TPS cable mm ² mean?
The indicators we often refer to as tps1.5mm, tps2.5mm, tps4mm, tps6mm, and tps10mm square wires refer to the cross-sectional area of the wires. A 1.5 square meter wire refers to a wire with a cross-sectional area of 1.5 mm ². When we choose TPS cable sizes, there is also an indicator - current carrying capacity. Current carrying capacity is the maximum current that a conductor can continuously carry per unit cross-sectional area under specified conditions without causing its stable temperature to exceed the specified value. The safe current carrying capacity of general copper TPS electrical cables is 5-8A/mm ², and the safe current carrying capacity of aluminum wires is 3-5A/mm ².
For example, the recommended maximum safe current carrying capacity for 2.5 tps cable copper wire is 2.5 × 8A/mm ²=20A, and the recommended maximum safe current carrying capacity for 4mm tps cable copper wire is 4 × 8A/mm ²=32A.
2, How to choose TPS cables for home decoration?
In specific practice, for example, if a 1000W electrical appliance needs to be connected, I=P/U=1000/220=about 5A. Usually, a current carrying capacity of 1mm ² is about 5A-8A, so one square meter of wire is sufficient. Of course, the premise is that the national standard copper cable, and if it is aluminum, it should be at least 1.5mm ².
Lighting:
1.5 TPS cables are commonly used as lighting circuits in home decoration to ensure the use of lamps with a maximum power of around 2500W. For some bathrooms equipped with bathroom heaters, the power may reach several hundred W or even thousands of W. It is recommended to replace the lighting circuit with a 2.5 TPS cable to ensure the safe use of lamps and bathroom heaters with a power of around 4000W at the same time.
Socket:
Other household sockets commonly use a 4 tps cable, which can be connected to appliances up to 7000W with a maximum voltage of 220V * 32A for safe use. Lighting and socket circuits should be used separately and should not be powered from the lighting circuits. They should be used as sockets, and standards and regulations are a prerequisite for safety.
air conditioner:
It is recommended that the air conditioning unit be wired separately from the electrical control box, as residential socket wires are mostly connected in series. It is not recommended to let the circuit run at full load, which can accelerate aging and increase risks. Air conditioners with 3 horsepower or more generally use single core wires with 4 TPS cable or higher specifications.
Instant water heater:
Instant water heaters are popular due to their energy-saving, compact and beautiful design. They are currently becoming popular very quickly, but they also consume a large amount of electricity during operation, ranging from as little as 3000W to as much as 6000 7500 8000W or even higher. Therefore, for the installation of instant water heaters, if the power exceeds 6000W, it must be separately wired from the electrical control box. If the power exceeds 7000W and is below 10KW, a 6mm TPS cable should be used, and a corresponding current anti leakage air switch should be selected. The brand of wire and cable should be chosen, and it is not advisable to save money to avoid danger during use.
The above is the introduction by the editor about what TPS cable means and how to choose TPS electrical cable for home decoration. When choosing, it is also necessary to consider the actual decoration needs and choose the appropriate cable. Choose a legitimate purchasing method, and the products purchased must have SAA certification. Do not purchase counterfeit and inferior products for the sake of cheapness.
