Tronic Manual Changeover Switch 32A
TSh 86,500
Our review
A manual changeover switch is the piece of equipment that lets you move your supply from the main grid to a backup source, such as a generator or inverter, without rewiring anything on the spot. This Tronic unit is rated at 32A, which puts it in the range typically used for smaller premises: a shop, a workshop, a small office, or a home where only selected circuits need to stay live. It is operated by hand, so someone has to be present to flip it when the power goes and again when it returns.
Before buying, work out your total load. Add up the current drawn by everything you want to keep running and make sure it sits comfortably under 32A, because a switch that is constantly at its limit will not last. Also confirm whether your backup source is single or three phase, and check the number of poles you need, since a changeover switch has to match the wiring arrangement you already have. An electrician should install it and verify the earthing and isolation.
Compared with automatic transfer switches, a manual one costs less and has fewer parts that can fail, but it depends on a person being there. If your outages are frequent or happen overnight, an automatic unit may suit you better. If you mainly want a simple, dependable way to switch over during planned or short outages, this is the more straightforward choice. It is available on Sokonia.
