They whole subject of 'Maintenance Free' (MF) is broadly not well understood and can therefore be said to be a grey area. SpliceLine, like all other Push In style connectors, are not officially 'Maintenance Free'. SpliceLine and Push-In wire connectors for solid and stranded copper cables are widely perceived in the market as maintenance free, even when used in conjunction with or without a suitable enclosure. Although the connectors themselves are not maintenance free, they are certainly much easier to use / install and are definitely considered to be safer than traditional methods of joining wires, ie; connector blocks with screw terminals. There are a small number of dedicated connector enclosures on the market which are rated as 'Maintenance Free'. Some are not designed for use with separate Push-In connectors as they have pre-fixed terminals already inside the enclosure itself. To use Push-In connectors to qualify as maintenance free, they must be used in conjunction with a suitable 'maintenance free' enclosure. IDEAL is currently working on developing such an enclosure to offer a truly 'Maintenance Free' solution. We hope this answers your question and is helpful.
