AJ Power were approached by a company who needed to provide backup power to an apartment block consisting of eleven apartments and a communal area. Simple enough, you would think.

However it became apparent as we prepared the solution for the customer that one ATS would not be a viable option at the main incomer, as all the electricity meters would continue operating even when the genset was supplying the load. The solution, a custom built ATS with a change-over system, eleven ATS switches (10 x 63A and 1 x 250A) which were linked together and controlled by one ATSc controller. All this was housed in a modular floor standing enclosure to allow easy connection for all the bottom cable entries. Workmanship doesn’t get much better than this, wouldn’t you agree.
