No bone about it — Induction cooktops are now common in many households, restaurants, and cooking shows. They are powerful, fast, efficient, and easy to use. But there’s little info about induction cooktops electrical requirements — voltage, power, and temperature.
We want to find out the electrical requirements of using an induction cooktop. Read On!
What are the induction cooktops’ power requirements?
Induction cooktops are energy efficient and have heat consistency. However, different cooking tops have varying uses hence have different energy requirements.
The differences are clear in the induction top’s design, size, and features. By extension, the power needs may vary from one induction cooktop to another.
Here’s a simple explanation. One burner tops will consume less power compared to five burners. You need specific temperature settings, electricity input, and voltage for your cooktop. In any case, induction cooktops can work with the standard voltage supply of 120-240 V.
The voltage that a stovetop needs determines its watt rating and circuit requirements. The three factors work together. So, consider your cooking needs when buying a cooktop by checking its cooking temperature.
For instance, a single burner with a wattage rating of 1200 – 1800 W will need a circuit that supports 15 amps.
Multi-burner cooking tops have a high wattage rating hence need a higher amps circuit. The circuit rating for a 4 or 5 burner induction cooktop will shoot to 40 – 50 amps. In summary, the final cost will vary depending on your usage.
Do induction cooktops need special wiring?
This is a common question from induction cooktop users. Your induction cooktop does not need any special wiring. All you need to do is plug your induction cooktop into an electric power source, and it should start working.
Your induction model and the wiring in your home will still determine if you can plug and use your stove. Differences in amperage capacity and your induction needs may call for special wiring. If it gets to this point, here are few things to keep in mind before wiring the induction hob.
a) Have a clear knowledge of your building code
Ensure that the wiring complies with the national electric code before any wiring installation. Your circuit needs the correct voltage, frequency, and amperage. This is dependent on a dedicated grounded circuit. You must also ensure that the circuit has a fuse or an appropriate circuit breaker.
b) Be sure of your power supply connections
Confirm if you have a three or four wires connection. Despite the number of wires, ensure that your neutral grounding comes from your local codes.
c) Check if you need special connectors
At this point, pick high resistance wires for the current to flow. Low resistance wire will let the current would flow in any direction. So, the copper wiring in the cooktop should be compatible with any other wiring in your home. A disparity in this would call for expert connection using special connectors.
How many amps does an induction cooktop need?
Do induction cooktops need a 3 phase power? Induction cooktops don’t need three-phase power. In most cases, induction cooktops work on single phase 220-240 V AC, 50-60 Hz.
But, electric intensive induction cooktops may call for a three-phase power installation. Such a three-phase installation needs a earth connection based on applicable electrical codes.
Do induction cooktops require 220?
Most induction cooktops don’t need any special kind of connection beyond a 120-240 V outlet. However, you can mount a 40-50 amp breaker near the cooktop to protect the circuits.
Caution: You need to take care to avoid exposing the breaker to excessive heat. This means that the junction box should be a reasonable distance away from the cooktop.
The good news is that most manufacturers have a length of flexible armored cables. You can connect the cooktop to the home wiring at the junction box.
Can you plug an induction hob into a normal socket?
Yes. There are several configurable hobs on the market that allow a variation of supply power. This improvement creates room for a typical socket configuration to accommodate more connections. With this improvisation, several hobs can use a standard 13 amp wall socket.
Also, the market has many hobs that work with a standard wall socket. There are hobs as well that are hardwired into a dedicated circuit. Some even come with an already attached 3-pin plug. The twist to this is that when the stove draws the maximum 13 amp supply the rings share the power between them.
Do not get it twisted. Hobs with 3-pin plugs still need lots of power. For that reason, you need a dedicated circuit for your induction unit. You can do so by creating a radial circuit in the kitchen by breaking one of the rings.
Do induction cooktops use a lot of electricity?
No, induction cooktops don’t consume a lot of power. Although you connect them to a direct power source, they use less power. Induction units use the magnetic property of steel to heat the cooking vessel. The heat spreads evenly and faster than gas cooktops.
Check the label at the back of the cooktop if you want to know the electric consumption of your device. For instance, a 2000-watt label means your hob uses 2 units of electricity in an hour.
You can also use a KillAwatt device to know how much electricity your stove uses. This device will tell you the exact electricity consumption.
Does an induction cooktop need an isolation switch?
Yes. Induction cooktop manufacturers recommend to have an isolation switch on your unit. Mark and mount the switch in a visible and accessible position.
It is also advisable to switch it on every time you are incorporating gas or electric sources of energy. The switching device should operate in all live conductors, whether active or neutral!
Some people may find the isolation switch distracting. Always remember its use though.
What should be the wire size for an induction cooktop?
The size of the wire is important in carrying a specific amount of current. Always check the diameter of the wire and the rating of its resistance. Pick the correct size of the wire according to your local wiring codes.
Your area’s local regulations usually specify the gauge. Below are some near-standard values to give you a feel of what we are talking about.
- 14 gauge — 15 amps
- 12 gauge — 20 amps
- 10 gauge — 30 amps
- 8 gauge — 50 amps
- 6 gauge — 65 amps
An 8 gauge wire would be ideal for wiring or rewiring your house. It will give you a dedicated 50 amps for your induction cooktop. When doing the cooktop wiring, switch off power from the circuit. You’ll avoid getting electric shocked or causing a fire.
Final thoughts
For lightweight and normal cooking, induction hobs are energy efficient. Also, you’ll enjoy speedy heating, many cooking controls, and safe cooking. You do not need any special electrical wiring to run a hob. Low gauge wires will only be handy if you’re operating a big induction stove.
