The 2011 NEC, Article 406.4(D)(4) requires AFCI protection to be installed when a receptacle is replaced on a circuit requiring AFCI protection. There are a lot of manufactured homes here in Florida, but I can not find a similar requirement in Article 550. Am I correct in thinking the provisions of 406.4(D)(4) do not apply to manufactured homes?
When Ohio regulated MHs in 2007 we were told/taught that after one year, if on a permanent foundation, that the MH was under the RCO. That means the same as any other single family home. Your state may treat them that way.
But let's stay with the NEC.
