MC4 Safety Locking Sleeve
The pluggable safety lock clip secures the PV plug connection. Use the MC4 Locking Sleeve when solar modules are equipped with Multi-Contact MC4 connectors. In order to comply with the 2008 National Electric code for accessible arrays, the plug connection must be secured with the UL approved, pluggable safety lock clip (PV-SSH4). Once the clip is installed, the PV plug connection can only be unlocked using the MC4 Disconnect tool .
