Electric ranges
Electric ranges were filed apart from gas ranges. The fuel decides the circuit. An electric range is a 240-volt appliance. The receptacle is not the 120-volt outlet a gas range uses for its igniter.
Coil, glass, induction
A coil top has elements that lift out for cleaning. A radiant smooth-top hides the elements under glass and wants a flat pan. Induction heats the pan with a magnetic field, so a magnet has to stick to the pan, and the glass stays cooler except where the pan sat. All three still land on the same 240-volt circuit. The catalog did not give them three departments.
How the oven joins the top
A freestanding range includes a backguard and sits on the floor. A slide-in has no backguard and meets the counter at the sides. A drop-in hangs from the counter and has no storage drawer underneath. A cooktop over a drawer is a different product. If the kitchen has a separate wall oven, this shelf is the wrong one.
Widths cluster around 30 inches, with narrower apartment sizes still made. Measure the cutout, not the face of the next cabinet. The cord leaves the back, and a tight wall will pinch it if you shove the range home before the plug is in.
