EcoCable 20' Multi-Contact MC4 Solar PV Cable - #10 AWG
These cables have the newer, snap-together Multi-Contact hard plastic connectors on each end and are made with PV-Wire that has an extra layer of insulation for use on ungrounded arrays in conjunction with transformerless inverters.
All cables are manufactured with #10awg PV Wire, which is UL 4703 rated and double jacketed/insulated. PV Wire is now needed for ungrounded arrays in conjunction with transformerless inverters. This type of wire is required to meet the 2008 NEC if you are using a transformerless inverter.
