Removing 7301/301's from Amalgamated Electric fuse box.
 
Before I begin, I am planning on replacing the fuse box with a breaker panel when we do some reno's in the house in the near future. I just need another couple of circuits and would like to repair the fuse box to make it safer for now.

I have an old Amalgamated Electric fuse box with 7301/301 plug in type fuse holders. I have a couple of damaged holders with the barbed contacts to the busses. Is there is a quick and dirty trick to remove them? Pulling them straight out doesn't work (even with persuasion). One of the contact blocks (? wrong term) is broken so I need to pull all the fuse holders, slide the contact blocks all off, replace the broken block, and put the fuser holders back in.

There must be a quick and dirty trick to it that electricians that have dealt with these panels must know?

My safest suggestion is it is good time to plan to replace the old fuse box due you mention you going to renoviation the house.

even thru if you get the old fuse box fixed IMO it still not really safe sometime with the repairs it done it can get worst if not done right.

So ., therefore it will be good move go ahead and do the new load centre installement so that way when you do the renovation it will become more eaiser to deal with the exsting circuits and bring them up to the codes as well.

Merci,Marc

I have already spoken to electricians about replacing the box with a panel, so that will happen.

Here is what I'm trying to resolve before that;
1) The fuse box is currently horizontally mounted and I would like to put the breaker box vertically. As a result some of the runs would not be long enough so I am replacing the wire to the first junction box and leaving a loop above the fuse box.
2) Some of the circuits were very unbalanced (half the house including the kitchen, bathroom, and computer room are on one circuit, but the doorbell has its own fuse). I'm trying to do some rebalancing before I put the panel in.
3) I need a couple of new circuits for a room in the basement I am finishing.

Once have saved up to do the kitchen reno's, I'm going to get an electrician in to do the panel and wire the new kitchen/dining room. I don't want him to have to mess around with stuff like fishing longer wire for the panel.

So that is why I am back to my original question, is there a trick to removing a 7301/301 with the barbed connectors?

That part number means nothing to me but most residential fuse panels are basically the same; 2 pull-outs up top with a number of fustats below. Are you taking about the fustat adapters that screw into the socket to ensure only the proper size fuse for the wiring being served is used? If you are there is a tool from a company called Trico made to remove them but it is unlikely you will find it any more. So to remove the adapter you have to first turn off power to the entire panel, with a small tip regular screw driver go around the lip of the adapter and bend it outward all the way around, you can also bend a piece of it up and grab it with a pair on needle nose pliers and turn the pliers to peel the rim all the way around. Once you have removed the rim you need to pull out the black plastic insert. If you peeled the rim right it should pull out fairly easy but it can be difficult. Once you have removed that look inside the screwshell and you will see the barb that doesn't let you unscrew the shell. Take your screwdriver and pry it out and then unscrew the inner shell. You are now able to tighten the screw that holds the fuse socket to it busbar and replace the fustat adater with a new one or use a fuse that fits the screwshell without the adapter. If the socket is damaged below the adapter you probably shouldn't use that space.

I should have included a picture I suppose. When I walked into electrical supply places here, they recognized it immediately and referenced it by number. Here is a link to what I need to change.

There seems to be two types of these fuse holders. One type (as in the pictures above) is held in place with pressure of the connection to the buss. The other type have a small barb that hooks under the buss to prevent it from coming out. The newer ones seem to be pressure held (possibly to make replacement easier).

Some of the plastic around the metal where the fuse screws in has broken on a couple of these. I have new fuse holders, I just need to get the old ones out and then snap the new ones in place.
