Analysis by Dr. Electricity Ttengchu Insight Channel Why Did the Eunma Apartment Fire Occur? If electricity was the cause, the fire likely occurred for these reasons. Induction cooktops, one of the latest trends in kitchen environments, are gaining high popularity in terms of efficiency and safety. However, when remodeling existing buildings, many consumers and construction professionals are curious about whether induction cooktops can be used due to compatibility issues with electrical facilities, particularly in older homes. Based on in-depth coverage by the electrical specialist YouTube channel ‘Dr. Electricity Ttengchu’ Insight Channel, we will examine the feasibility of using induction cooktops in remodeled construction sites. 1. Starting with an Understanding of Induction's Electrical Characteristics Induction ranges operate on the principle of heating metal containers using the magnetic induction phenomenon generated by electricity. This requires a stable supply of high-output power, and the electrical system must be capable of handling this sufficiently. Generally, residential induction cooktops often require a power capacity of 2kW to 3.7kW or more, so insufficient electrical capacity issues may arise depending on the wiring conditions of existing homes. The channel "Electric Doctor Ddengchu" emphasizes checking the capacity of existing electrical wiring and distribution panels, as well as verifying the specifications of earth leakage circuit breakers (RCCBs) and short-circuit breakers, especially at remodeling construction sites. They advise that professional inspection must be performed beforehand, as insufficient or excessive capacity can cause problems with the stable operation of the induction cooktop. 2. Existing Wiring Conditions and Induction Compatibility Issues Many older homes have wiring installed with low specifications of 1.5mm² or 2.0mm². This is highly likely to be unsuitable for supplying the high-output power of 3.5kW or more required for induction cooktops. Furthermore, in a single distribution panel environment where multiple appliances are connected to the same circuit rather than using dedicated circuits, the risk of overload can increase. In fact, "Electric Doctor Ttengchu" advises that when remodeling to use induction cooktops, it is recommended to replace existing wiring with one of at least 3.5mm² or 4.0mm² and to install a dedicated circuit and circuit breaker for the induction cooktop. This is not only a matter of safety but also an essential condition to reduce power loss and the risk of failure when heating the induction cooktop. 3. Consider Replacing Distribution Panels and Circuit Breakers If an increase in electrical capacity is required at the remodeling site, the capacity of the circuit breakers in the distribution panel must also be re-evaluated. When using induction cooktops, it is safer to install circuit breakers of 20A or higher, and replacing earth leakage circuit breakers with the latest standards is effective in preventing safety accidents. "Electric Doctor Ttengchu" explains that updating wiring and circuit breakers may be more difficult or costly than planned, especially when the distribution panel space is limited; however, he emphasizes that improvements are absolutely necessary because this is a matter directly related to safety. 4. Other Electrical Facility Inspection Items The YouTube channel specifically recommended checking the electrical grounding status when using induction cooktops. For a standard earth leakage circuit breaker to function properly, the grounding work must be well-done; using an induction cooktop with poor grounding can significantly increase the risk of electrical leakage and electric shock accidents. Additionally, it advised that when using induction cooktops alongside other kitchen appliances, such as LED lighting or electric rice cookers, an integrated design is necessary, taking into account the capacity of the earth leakage circuit breaker. 5. Is Induction Cooktop Use Possible in Remodeled Buildings? In summary, the immediate installation and use of an induction cooktop during remodeling depends on the condition of the existing electrical facilities. In particular, older homes require essential steps such as wiring replacement, dedicated circuit configuration, replacement of distribution panels and circuit breakers, and reinforcement of grounding work. To ensure safety and efficiency, on-site inspections by electrical experts and design modifications must be performed. This goes beyond a mere issue with the induction appliance and is directly linked to the electrical safety of the entire build...
