When I started doing residential work, I always DID call PSE+G to notify them if I cut a seal. The response was always along the lines of "only we can break the seal, we'll get out there a week or 2 from now" (meanwhile the customer is without power), or the exact opposite "go ahead and cut it, and why are you bothering to call?". It completely depended on who you happened to talk to, or what office you were dealing with.
I bought a few of the wire/plastic seals identical to the ones PSEG uses from McMaster/Carr, and use them to reseal, along with leaving the old seal and a business card hanging on the meter. No complaints so far....
