Frequently Asked Questions
Can the FuseBox SCO125SWB be used with a backup generator?
The SCO125SWB may be suitable for generator changeover arrangements where the installation has been designed to accommodate a compatible manual changeover switch.
A correctly configured changeover system allows selection between the normal electrical supply and an alternative source, helping prevent the two supplies from being connected together.
However, generator compatibility depends on several factors, including voltage, current, earthing arrangements, neutral switching requirements and the overall electrical installation design.
A qualified electrician must confirm that this particular switch is suitable before it is incorporated into a generator backup system.
Does the switch automatically change to backup power during a power cut?
No, the FuseBox SCO125SWB is a manually operated changeover switch.
It requires the switch to be operated to select the appropriate power source.
It does not automatically detect a power failure, start a generator or transfer the electrical supply without user intervention.
If automatic power transfer is required, a purpose-designed automatic transfer switch system would be necessary.
Can I install this changeover switch in an existing consumer unit?
The SCO125SWB is designed for DIN rail mounting, but this does not mean it will fit or be compatible with every consumer unit.
The existing enclosure must have sufficient space, suitable connections and the correct electrical configuration for the switch and supplied busbar.
Compatibility with the consumer unit, its protective devices and busbar arrangement must be confirmed before installation.
A qualified electrician should assess the existing equipment and determine whether the switch can be safely incorporated or requires a separate suitable enclosure.
Does the included busbar replace the need for separate wiring?
The supplied busbar provides a convenient connection component for compatible electrical distribution arrangements.
However, it does not eliminate the need for correctly sized conductors, suitable terminations and other connections required by the installation.
The electrical layout, current rating and compatibility of the busbar must all be checked before use.
All connections must be installed in accordance with the manufacturer's instructions and applicable electrical regulations.
Does the 125A rating mean the switch can be used with any 125A electrical supply?
No, the 125A rating indicates the switch's stated current capacity, but suitability depends on more than current rating alone.
The installation must also be compatible with the switch's voltage rating, switching configuration, load characteristics and applicable electrical protection requirements.
Other considerations include cable sizing, prospective fault current and the suitability of the electrical enclosure.
A qualified electrician should verify the complete technical requirements before selecting the switch for a particular installation.
Does the IP2X rating make the switch suitable for outdoor use?
No, an IP2X rating does not mean the switch is waterproof or suitable for direct exposure to rain and moisture.
IP2X indicates protection against access with a finger and the entry of solid objects of a specified size, but it does not provide a rated level of water protection.
For outdoor or damp environments, the switch must be installed inside a suitable enclosure with an appropriate IP rating for the location.
The complete installation should also meet the applicable electrical safety and environmental requirements.
