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.
The economic and monetary situation in Cuba is quite complex, for a start there are 2 currencies 1  : The Peso Convertible-CUC-the main currency used by tourists. 2  The Peso Cubano-CUP (or M.N-moneda nacional) - used mostly by Cubans at places like ration stores.t present, the only cities in Cuba with ATMs are Havana, Camaguey, Trinidad, Cienfuegos and Santiago de Cuba. You will need a pin number on your credit card to be able to use the ATMs. We find occasionally that people come to Cuba with a Visa âdebit cardâ that does not work in the ATMs.
