Remark:
1. H: Height, D: Diameter, a: Width of Base Plate, b: Length of Base Plate. H X D is maximum dimension, a X b is standard dimension.
2. This size is HDB series  (wire total in Copper), size of HDBLL series (wire total in Aluminum) , HDBL, HDB L-L series  (wire in Copper cladAluminum ) is larger a little than this.
3. Dimenstions freely adjustable.
