Square D I-Line Panelboard 600 Amp 120/240V Single Phase With Breakers . Condition is New. Shipped with USPS Priority Mail. This panel will arrive with new panel cover installed. This is a 600 amp main lug panel only. Panel will not support a 600 amp main breaker for feed thru. Panel will only support as big as a 225Amp branch breaker. It has lugs install on all 3 buss bars. All breaker in panel are set up for A and C phase so all other breakers need to be the same way. Sorry for the long description, was returned due to an un-educated individual.
