How to Choose a Changeover Switch in Nigeria
A changeover switch transfers a load between mains, generator or another approved source. The correct product depends on the installation current, supply phase, number of poles and the switching method required.
Manual, on-load and MCB changeover options
Manual enclosed changeovers are common in homes and small premises. On-load switches are designed for controlled switching under their stated duty, while MCB changeovers combine compact switching with a breaker-style format.
- Manual enclosed changeover
- On-load changeover
- MCB changeover
- Confirm the enclosure and pole configuration
Select the current rating correctly
The amp rating must be checked against the incoming supply, calculated load, cable size and upstream protection. A qualified electrician should confirm the rating before installation.
- 32A and 63A for many smaller installations
- 100A and above for larger loads
- Single-phase or three-phase supply
- Coordination with cables and protective devices
