10-step safe isolation cycle, neutral back-feeds, UPS supplies, and solar PV isolation safety.
Vauxhall research indicates the number of UK councils offering accessible on-street EV charging has doubled in the past year. However, three-quarters of local authorities still lack dedicated accessible charge points, according to Freedom of Information data.
Martindale Electric warns that safe isolation alone does not eliminate all hazards, specifically noting the risk of injuries from unexpectedly live metal parts. The company urges engineers and contractors to remain vigilant against these additional dangers when working on electrical systems.
Flexson has launched the In-Ceiling Mount (FLXE100ICM1011) for Sonos speakers, allowing installers to create discreet audio installations without an amplifier or equipment rack. The new accessory is compatible with Sonos Era 100/SL, Era 100 Pro, and Sonos One/One SL models.
