Marathon Special Products’ new group of UL-recognized Power Terminal Blocks is ideally suited for combiner boxes of solar power systems. These blocks are comprised of a compact, one-piece terminal that’s sized for small solar panel wires, and can combine up to 24 or 48 strings to distribute 310 to 620 Amps respectively at 90° C (194° F) wire ampacity. Previous power block options left panel builders with terminals sized for #4 AWG wires, which are larger than typical solar panel strings need (#10 AWG or smaller). Marathon’s new power blocks have multiple #8 AWG terminals that take up half the space of current options, while providing the dielectric clearances needed for 1000V per UL1741. The large number of terminals per block also eliminates the need to wire or assemble multiple components together to create a suitable combining device.
