Finding intermittent faults that take out fuses when youa re somewhere else in the shop can be a pain to catch...The point of my light bulb across the breaker/fuse is the light turns ON when the breaker pops and this is very handy when you are elsewhere in the shop and the fuse is on an intermittent circuit.
Cuba: Electricity. Although the power supply in Cuba is mainly 110 volts, most of the modern hotels have dual voltage with all the sockets in the room being 220 volts. Usually in the bathroom there is an 110 volt socket suitable for shavers and charging batteries. A 4 gang 13 amp extension lead could well prove very useful.
Electrical sockets (outlets) in the Netherlands Antilles (Dutch West Indies) are one of the two European standard electrical socket types: The Type C Europlug and the Type E and Type F Schuko.lectrical sockets (outlets) in the Netherlands Antilles (Dutch West Indies) usually supply electricity at between 220 and 240 volts AC. If you're plugging in an appliance that was built for 220-240 volt electrical input, or an appliance that is compatible with multiple voltages, then an adapter is all you need.
