Quick questions on services. I upgraded a 100a to 200a residential service. I moved the service over about 3 foot to get the proper clearance for the drip loop due to the structure of the home. I left the old 100a meter base up on the home disconnected all wires going to it and blanked off the meter socket.(left it on because it was sided around and would leave a ugly hole) I was told by my supervisor that this is illegal and all old service equipment must be removed. Is this correct? He couldn't give me a code reference and I looked in the code and can't find one. Also if anyone knows what the code reference to labeling the panel on a service change out.
Thanks.
Thanks.
