One of the jurisdictions we work in started requiring fireproof putty patches that wrap around the box to be installed in fire walls. They are only requiring them in electrical boxes, not phone or fire alarm. I am used to the requirement that they have to be wrapped if they are within 24 inches of another box (on the horizontal plane only, not vertical), but now they are saying all electrical boxes. They claim to have been requiring them all along, but we have working in that jurisdiction for around twenty years and have never been required to do it before. Another strange thing is that we had already passed the electrical inspection and it was the building inspector that required it. When we called the electrical inspector about it, all of a sudden he agreed with the building guy.
Is this something that all of a sudden the inspectors got together and decided to start requiring?
