How to Select 3G 6 sq mm Cables for the Connection of Electric Hobs
Precision and adherence to standards are required for electrical setups to guarantee safety and efficiency. Among the common choices, Electrical Cable 3G 6mm2, providing reliability and multifunctionality, remains the most widely used option for medium to high power applications. We Vocson offer high-quality electrical cables that ensure compliance with these standards, making installations both safe and efficient. And, we are introducing this guide that dives into its specifications, uses, and considerations, helping you make decisions for the time and the way of effective use.
What does Electrical Cable 3G 6mm2 specifically refer to?
The term 3G 6mm2 offers valuable definitions to the construction and capabilities of the cable. The name can be broken down into:
- “3”: This number indicates that there are three insulated copper wires in the cable.
- “G”: It means one of the wires is green-yellow, and used for maintaining the safety of the grounding wire.
- “6mm²”: It refers to the cross-sectional area of each wire, serving a critical role in deciding its current-carrying capacity.
All in all, 3G 6mm2 can be named as 3x 6mm² as well. Different from 3G 6mm2, a 3G 10mm2 cable includes wires with a larger cross-sectional area of 10mm², fit for higher power requirements.
NF C 15-100 Standard for Electrical Setups
When linking a ceramic hob, compliance with the NF C 15-100 standard is vital. This standard mentions the demands for electrical setups in residential as well as commercial buildings for the sake of safety and reliability. Some main points are related to 3G 6mm2 cables:
- Circuits like a hob must be linked to a specialized 32A outlet. It is the max current the cable can carry in a safe way.
- A minimum cable cross-section of 6mm² for 32A outlets is needed.
- A 32A circuit breaker is needed for setups using 326mm2 cables, which provides protection against overload.
Though the standard offers guidelines, knowing the specific power demands of your appliance is critical. Factors like amperage and wattage are vital to deciding if a 3G6mm2 cable fits.
Amperage Calculation for Ceramic Hobs
Instead of amperage, manufacturers usually specify the power of a ceramic hob in watts (W) or kilowatts (kW). To decide the current (amperage), the following formula should be used:
P=U×IP = U \times IP=U×I (Power = Voltage × Current)
Definition:
- P = Power in watts
- U = Voltage (230V for single-phase systems)
- I = Current in amperes
Example Calculation
For a ceramic hob with a power rating of 7200W:
- Voltage: 230V
- Current: I=P/U=7200/230≈31.3AI = P / U = 7200 / 230 \approx. 31.3AI=P/U=7200/230≈31.3A
This amperage is in the capacity of a 3G 6mm2 cable, which suits hobs with similar specifications.
Can 3G 6 sq mm Cable deliver constant power?
While 3G 6mm2 cables provide enough electricity for most ceramic hobs with power ratings up to 7200W, an upgrade of capacity may be required by many robust household appliances.
For High-Powered Hobs
A 5-burner ceramic hob with a total electricity of 8500W can be chosen:
- Current: I=8500/230≈36.9AI = 8500 / 230 \approx. 36.9AI=8500/230≈36.9A
In this circumstance, a 3G 10mm2 cable and a 40A circuit breaker are needed to withstand the load safely.
Which to Choose, Flexible VS Rigid Cables?
When picking out a 3G 6mm2 cable, two main options are commonly available: flexible as well as rigid cables. Each one has its benefits according to your specific setup demands.
Flexible Cables
- It is built of refined copper strands, providing high flexibility.
- Benefits: They are able to maneuver in limited spaces, which makes them fit for residential setups.
- Recommendation: It is advisable to link hobs to electrical panels for the sake of ease of handling.
Rigid Cables
- They are comprised of solid or interlaced copper wires.
- Profits: It has high durability for fixed setups where movement is minimal.
- Scenario: It has widespread applications in industrial or underground settings.
Installation Guides for 3G 6mm2 Cords
Proper setup guarantees the cable functions in a safe and efficient manner. Some practical tips are listed below:
Preparation:
-
- A cable stripper can be employed to remove insulation without causing damage to the wires.
- Cable end caps should be compatible with flexible cables to tighten the copper strands.
Connection:
-
- Check the compatibility that the cable should be matched with a 32A circuit breaker.
- Secure connections should be confirmed to avoid overheating.
Testing:
-
- Load tests should be conducted to make sure the cable has the ability to withstand the high-power demand of appliances.
- A multimeter should be used to inspect for continuity and proper grounding.
Price Comparison between 3G 6mm2 and 3G 10mm2 Cables
3G 6mm2 Cable
- Per meter (cut): 5-6 dollars
- Per meter (roll): Approx. €2 (better value for larger installations)
3G 10mm2 Cable
- This type of cable is relatively more costly because of the larger wire cross-section but is vital for high-power applications.
Spending on the right cable guarantees safety and compliance with electrical standards, helping reduce costly replacements or upgrades.
Practical Applications of 3G 6mm2 Cable
The applications of 3G 6mm2 cables can expand to other high-power appliances, though they are widely used for hobs:
- Water Heaters: They are ideal for sending consistent electricity to heating units, ensuring the efficiency and safety of power delivery.
- Air Conditioners: These are fit for single-phase AC systems that cover within their amperage limits.
- Power Tools: These are universally applied in workshops to deliver stable electricity to industrial-grade equipment.
- Industrial Machinery: 3G 6mm2 is commonly found in medium-size machinery installations where steady and powerful electrical connections are needed.
In addition to traditional applications, 3G 6mm2 cables have been increasingly found in modern installations, mainly in:
