So this is what you have: Panel feeds junction box with EMT- From JB to various loads with MC cable. The box is grounded via the EMT. If over 250 volts and concentric or eccentric KO's are used with the EMT than a bonding jumper is required. The EGC within the MC cables are required to be bonded to the box.Eventually you'll notice a drawer makes an awful metal on metal sound when you open it or a chair no longer rolls smoothly. As long as their no pets or kids that are going to eat them, just keep picking them up as you find them.
