16. You see a group of small fuse holders on a DIN rail in an industrial control cabinet. The fuse holders are in groups of five and are separated by a single terminal block. What's connected to that terminal block? A. System ground B. A control signal C. The AC or DC power to the fuses D. The power supply neutral 17. Which one of the following types of raceway offers the greatest protection for the conductors in the raceway? A. Metal wireway B. EMT conduit C. Rigid conduit D. Flexible conduit 18. Class 1 conductors or cables may be run with other Class 1 conductors if they all A. are part of different machine circuits. B. have different power supplies. C. have reduced voltages on the conductors. D. have the same insulation value. 16. You see a group of small fuse holders on a DIN rail in an industrial control cabinet.
