What is the supply frequency in Barbados?
50 Hertz. (cycles per second)
What should be done when the lights are dimming?
Call our emergency line at (246) 626-9000. If they dim noticeably when the fridge cuts in or when you turn on an appliance then you may want to discontinue the use of the equipment until this is checked. If they only dim once or twice this may be due to a transient on the system. However, if you notice this happening regularly contact us or get an electrician to check it for you.
