What Size Cable For The Induction Range Cooker?


The size of the cable you need for an induction range cooker depends on the wattage of the cooker, the amperage rating of the circuit, and the length of the run.

For a 120V circuit, you need a 12 AWG cable for up to 20A or a 10 AWG cable for up to 30A.

For a 240V circuit, you need an 8 AWG cable for up to 30A or a 6 AWG cable for up to 50A.

The length of the run should not exceed 150′. If it does, you’ll need to go up one size in gauge for every 50′ beyond 150′. 

There are also two other important considerations – voltage drop and conductor resistance. Induction cooktops require a minimum voltage of 110V, so if your circuit is supplying less than that, you won’t be able to use the cooktop.

Voltage drop is the loss of voltage as it travels through the cable.

The greater the distance between the appliance and the breaker, the more voltage drop you’ll have. To compensate for this, you need a cable with lower resistance.

The resistance of a conductor is inversely proportional to the cross-sectional area of the conductor.

So, the larger the conductor, the lower the resistance. That’s why you need a bigger cable for a longer run.

There are several factors to consider when choosing the right size cable for your induction range cooker:

  • The wattage of the cooker
  • The amperage rating of the circuit
  • The length of the run
  • Voltage drop
  • Conductor resistance

What Size Cable Do You Need For An Induction Hob?

The size of the cable you need for an induction hob depends on the power output of the hob.

Most hobs have a power output of between 2kW and 7kW, so you’ll need a cable that can handle that amount of power.

The type of cable you need is also important – for induction hobs, you’ll need a conductor made of copper or aluminum.

So, to summarise, the size and type of cable you need for an induction hob depend on the power output of the hob.

Most hobs have a power output of between 2kW and 7kW, so you’ll need a conductor made of copper or aluminum that can handle that amount of power. 

Is 2.5 Mm Cable OK For An Induction Range Cooker?

2.5 mm cable is typically used for lower-wattage induction cookers (1,500 watts or less).

If your induction cooker has a higher wattage (2,000 watts or more), you’ll need to use a thicker cable, such as 4 mm. 

Some people believe that using a 2.5 mm cable on a high-wattage cooker can lead to fires, but there’s no evidence to support this claim.

In fact, the National Electrical Code (NEC) in the United States actually permits the use of 2.5 mm cable for high-wattage induction cookers. 

So, in answer to your question, yes, a 2.5 mm cable is OK for an induction range cooker, as long as the cooker has a power output of 1,500 watts or less.

What Size Cable Do I Need For A 7.4 KW Induction Hob?

As with all electrical safety questions, it’s always best to start by consulting with a certified electrician.

They will be able to take a look at your specific installation and appliance and advise you on the correct cable size.

In general, however, for a 7.4 KW induction hob, you will need at least a 4mm2 cable.

This is because the power rating of an induction hob can range from 7 kW to 15kw+, so you need to ensure that your cable can handle the maximum possible load.

If you’re not sure which size cable to get, it’s always better to err on the side of caution and go for a larger size.

It may cost a bit more upfront, but it’s better than having to replace a cable that’s too small and causes a fire.

What Is The Difference Between Copper And Aluminum Cables?

The two main types of electrical cables are copper and aluminum. They both have their pros and cons, but copper is typically seen as the better option.

Copper cables are more expensive than aluminum cables, but they have a number of benefits.

They have a high current capacity, meaning they can handle more power without overheating.

They’re also less prone to voltage drop, which is important for long cable runs. Copper cables also have a longer lifespan than aluminum cables.

Aluminum cables are cheaper than copper cables, but they have some drawbacks.

They’re not as durable as copper cables, and they can’t handle as much power.

They’re also more prone to voltage drop, meaning you may need a thicker cable if you’re using them for a long distance.

What Size Cable Do I Need For A Range Cooker?

You’ll need a 3-wire (plus ground) range cooker cable that’s at least 10 feet long. It should be an 8-gauge cable.
