Re: Ark Fault Breakers

In Minnesota, for work in existing dwellings, if the opening is 125 V, 15 or 20 A, new and in the bedroom, it must be supplied from an AFCI. So, new luminaire on a new outlet, new 120 V smoke detector where there hadn't been, new receptacle outlet. . .all get AFCI, which means a homerun when it could have been a simple extension. And if the panel is a fuse center or an off brand instead of the Big Four AFCI manufacturers, then a new subpanel must be installed for the AFCI.
