mismatched fuses
In addition to the fuse issue, the wiring from the switch does not appear to be 200A wiring (3/0 THHN)
" High Leg " conductor in a 240 volts three phase fuse disconnect shall be located at right terminal .
That's incorrect. That's only in service rated meter sockets. Everywhere else; in panels, on breakers, in disconnect switches, they "high" leg is in the center position.
The supply fuse clips are two small, i.e. the fuse tabs should fit inside the clips completely (securely).
The fuses are the wrong type. They need to be type 'R' to accommodate the rejection pins in fuse clips designed for the class to which the fuse belongs.They are also lacking the proper markings.
Looks like non rejection type fuse in rejection
type clip. Short circuit protection may be compromised
Rejection type fuse holders with wrong class fuses installed. Likely called for current limiting fuses.
fuse rejection feature in holder is defeated.
Fusible disconnect is designed with Class R rejection clips. Fuses installed are not Class R fuses.
A moron not an electrician put the fuses in That's whats wrong!!
The phase conductors are brought through separate knockouts.
The Handy man did it. now start arresting non licensed side jobers
Wild phase is required to be in the "middle" for fuse and switch gear. Only on right hand side in a meter socket - (Three Phase Self Contained 200/320A)
If this is delta with a high leg, the phase tape should be orange not red. This was a code change 20 years ago. Lots of things wrong here.
not being able to see all three wires, phase rotation could be counter clock wise, wire markers could be blue - red - black instead of black - red - blue. but the main thing here is the wrong type of fuse.
Thanks for getting some great discussions going!
Why do you all think this is a high leg, anyone think that it is a disconnect that they changed phasing on for motor rotation? Common people the fuses are the wrong type. Maybe wrong amperage too, the person who has done this must be a first year journeyman.
