OK, This is just an idea and may need some kicking about. would it be benifical to us sparks to put together a PIR code list. Lets see how we code them and then pick the average as a default. We could possibly refer to this in our PIRs as a guide. safe in the fact that we know at least that a good section of how I consider professional Electricians would code things. OK may be some work for admin but its a suggestion. Regards Jimbo
