An electric oven is a high-power kitchen appliance. Connecting it to an ordinary socket or extension lead can cause overheating, voltage drop, and breaker trips.
An oven can work under high load for a long time, so it often needs a dedicated line from the panel with suitable cable.
The breaker must match the cable and load. Upsizing a breaker without checking the wiring is unsafe.
When installing a new oven, seeing warm sockets, breaker trips, or renovating a kitchen, call an electrician for safe connection.
