More Residential Electrical Safety Tips

• Indoor distribution boards should be equipped with residual current devices.

• Avoid charging batteries for excessively long periods and do not leave them charging unattended.
• Never unplug appliances or operate electrical switches with wet hands to prevent electric shocks.
• Never plug a power strip into another power strip (daisy-chaining) to avoid electrical overload.
• If appliances or outlets show signs of abnormality, aging, discoloration, or overheating, stop using them immediately and arrange for inspection and repair.
• Always pull by the plug itself when disconnecting from an outlet and never pull the cord, as internal copper wires may break and cause a short circuit.
