If you are trying to save a decent amount of money on sub-distribution then you should definitely consider the Ellison Bantam solution.
Designed specifically for applications of 800A and below, Bantam offers a cost effective, flexible solution that reduces on-site installation time to a minimum.
Bantam is a compact design which can be used where space is at a premium and can be wall or floor mounted. The unit can cater for cables entering from above or below, and is suitable for use as either free standing sub-distribution load centres or multi-way outlets from Lambar rising main systems.
