We all know it shouldn't really be done, we have all done it when there was no choice or we know there was badge engineering going on, we have all seen pictures where someone has done it in a way thats clealy taking the piss, so post your worst photos here!

To start, this is one from a school science lab, the extra breaker feeds a projector socket

Thing is that up to about 3 years ago mix and match was VERY common but now it shouldn’t be 🤔

A few weeks back I ran in a sub main for some friends , ready for a builder and his “spark“ to do the bits for the garage conversion.

spot the extra circuit added by the other spark

and no certificates either
 
Another one, DB for a tea room in a truck workshop. Its made worse by the fact thaty its one of the wylex units that only has the top half of the DIN rail and relies on the busbar to hold the MCBs pulled downwards latched onto it, but busbar has gone and its been jumpered across with cable.

(The cicruit on RCD does have overcurrent protection, the feed comes off main switch into top and then loops off the bottom into the B32 next to it, in case your immediate thoughts were the same as mine)
