Greetings to all. Today I installed a switch box, which is to be used in case of a power failure. Under normal circumstances, when everything is in perfect order, you can safely forget about this switch. Don’t even touch him. But in the event of a power failure, it sets the time for which it was installed. If you use a generator, you need to switch the switch to position 2, connect an extension cable from the generator … and that’s it. A similar switch cabinet will also be installed for the main hangar door.
