Yes, convertible Main Lug Only (MLO) load centers are suitable for this application, but the short circuit rating is limited to 5,000 AIR. Only two-pole QO-H branch breakers, rated 240Vac may be used. The MLO cannot be converted to a Main Breaker panel and maintain the rating. Main Breaker load centers are not suitable for the application. Please refer to the Technical Information pages of Catalog Section 1100CT9901 for further information.
