325A MEM stuck Isolator

John- · May 8, 2022

Hi
Did some small works recently on a farm building, and the origin of the suppky is via the TPN isolator in the video. But it wont budge.

Any advice please?

I am extending the lever all the way out and then pulling down. I did not want to force it in case i broke sonething. It is the feed for the entie site.

Cheers
Jon

You need to close the cover.

video not working, plz see image’s . Btw door was not secured correctly, hinges were not engaged. Cover cannot be secured fully. I should also say it is stuck on, not off.

Yes I can see from your video it is on. What is wrong with the hinges.

Nothing is wrong with the hinges the door cannot be put back on properly unless the isolator is in the off position somebody has taken the door off and energised it and then loosely secured the door back on afterwards. I canot switch it off though to put the door back on properly. The mech near lever locks it off, not on.

Sorted it. I am guessing it had not been operated in years, a littje more brute furce needed. All mechs are well lubed, so must have been the the fuse blades.

Fuse blades also look good. Much less effort needed now, door interlock still works so didn't hulk smash that. Anyway better dash now, cows think there is an elegal rave with the lights going on and off - got any samon?
