To make full use of 40 kVA, both a 40 kVA and a 20 kVA installation distributor is required. Routing and symmetrical load distribution to both installation distributors will provide you with the full 40 kVA. As a result, you can supply 20 kVA to each of the two installation distributors, spatially separated on one exhibition stand or, as required, even on two exhibition stands.You can also operate the 40 kVA installation distributor on a stand-alone basis with an appropriate adapter on a 20 kVA connection.
