400 Volts Electrical Warning Signage

400 volt electrical warning signs help you alert electricians, contractors, maintenance staff and other people before they approach equipment or enclosures identified as operating at 400V. Use them on or beside switchgear, electrical panels, cabinets and distribution equipment where the voltage should be recognised before contact or access. Position the warning at the normal approach point so the electrical hazard is clear before inspection, maintenance or other interaction begins.
