Fuse puller for big fuses

Mr. Tool,

I do not like the ideal yellow pullers for this size, they either release the fuse half pulled, or bend your hands toward the holder during the re-insertion process. I have on occasion had to pull fuses under (minimal as I could make them) load, and certainly while energized.

But DC as you know is a different animal, having no zero crossing point. I will never pull one under any type of load, and will not pull one until I have read the amp meter for myself.

Now being on this forum I cannot recommend anything outside of absolute child proof safety measures. So I wont.

But I have heard that some people will insulate the handles on a large set of channel locks with many layers of electrical tap, and do the same thing to the jaws of these large channel locks and pull the fuses. One hard quick jerk and follow through with the arm to quickly break any arc that may follow.

Thats what I hear anyway.
 
The channellock idea crossed my mind yesterday... I can definitely achieve zero load, but didnt want to deal with the issues of re-installing the fuses.

Ive also thought of maybe getting 2 of the ideal fuse pullers to keep the pressure more even, but even that sounds sketchy.
It works well for re-install also.

If they are tanged fuses, snap in the dead side first, that will line everything up- then swing it in.

If they are round fuse clips, line up on the dead side and clip it in.

Channel locks have a much more assured feel and I am told work better then anything else in this type of situation.

But I would have Poco pull it all down first.
 


Something like this? Still not sure I would pull while energized but at least these grip better than the yellow Ideal pullers.

I used to use the identical pullers, but as mentioned there is a big enough pucker factor going on while pulling large DC fuses live. Those things do not grip tight enough, and by the second or third time of having one slip out while half pulled I abandoned that tool all together.

Upon insertion, again they do not grip tight enough. Either the handles try to bend, or the fuse twists getting your hand/forearm way to close to be comfortable.

You have to be very aware to pull and follow through to break any arc that MIGHT happen. I cannot think of much worse then having one fail to completely release if there was a load.

I trust 33 and the channel locks.
