I may not be an electrician but am compentent but do not give advice I always tell them to seek qualified persons advice even though I know what they should do. I am in full agreement with Concerned London. I'd like to add. IF YOU ARE NOT PROFESIONALLY TRAINED THEN DON'T GIVE ADVICE ESCPECIALLY ON ELECS, NOT EVEN LOW VOLTAGE, OR GAS.
Equally concerned at some advice.
