Not The Brightest Idea

We came to carry out an annual service visit at a client’s premises and it was necessary to load test the support battery in this PSU.

Unfortunately, since our last visit, the ceiling grid had been replaced, and we were now confronted with this situation.  The installers had failed to notice that this enclosure has a hinged lid! We just have to break it to the client, that it will have to be opened up.

Shame really, they had done such a good job cutting it around the box.
