elwood556 Posted July 25, 2007 Report Share Posted July 25, 2007 I found four defects in the panel, in the picture below. I was wondering if you guys can tell me what defects you see. I'm new to Home Inspection and would like your input to see if i didn't miss anything. Also the wires are all 14 gauge copper, and the white wire is one leg of a 240V circuit. Thanks.

There are five defects in that picture, but I'll bet that there are more than five defects in that panel. Do you have a picture that shows the entire panel? - Jim Katen, Oregon (Edited after I saw Fritz's response, cause I missed a defect.) Link to comment Share on other sites More sharing options...
homnspector Posted July 25, 2007 Report Share Posted July 25, 2007 Double tap, grounding conductor under a screw head, white insulated on hot, #14 on 20 amp fuse. Thats all I see. Link to comment Share on other sites More sharing options...
elwood556 Posted July 26, 2007 Author Report Share Posted July 26, 2007 I got what you found except for the -grounding conductor under a screw head. What is wrong with that? Another dumb newbie question. Thanks. --Are you saying its a defect because its not connected at a grounding terminal?? Link to comment Share on other sites More sharing options...

chicago Posted July 26, 2007 Report Share Posted July 26, 2007 Ok ..took me a few minutes but it looks as though besides being double tap the #14"s are wound around the screw and not behind the bracket. Link to comment Share on other sites More sharing options...
John Dirks Jr Posted July 26, 2007 Report Share Posted July 26, 2007 In addition to the other problems listed you have an unmarked white hot. Even though you recognized it as one half of a 240, it still should have a piece of black tape wrapped around the end right before it attaches to the fuse/breaker. A white can be used as a hot as long as it is marked. Link to comment Share on other sites More sharing options...

hausdok Posted July 27, 2007 Report Share Posted July 27, 2007 Hi Jim, If you're referring to S-type fuses, I've never seen that particular brand of fuse, but I'd thought that those were S-type fuses. OT - OF!!! M. Link to comment Share on other sites More sharing options...

OT - OF!!! M. If they are, then they've inserted the wrong adapter. With #14 wires on those circuits, there's supposed to be a 15-amp fuse protecting each one. If the proper safety adapter were there, those 20-amp fuses couldn't have been inserted into those fuse holders. - Jim Katen, Oregon Link to comment Share on other sites More sharing options...
Brian G Posted July 27, 2007 Report Share Posted July 27, 2007 Those aren't S types. You can clearly see the TD-20 catalog number on them. Type T, time delayed. Brian G. Fused To a T, Was It? [:-tong2] Link to comment Share on other sites More sharing options...
chicago Posted July 27, 2007 Report Share Posted July 27, 2007 Hang on a minute. Which came first the chicken or the egg? Perhaps the fuses are fine but the wire is wrong.lol Link to comment Share on other sites More sharing options...
StevenT Posted July 27, 2007 Report Share Posted July 27, 2007 If the white wire is one leg of a 240 circuit, isn't that the same as a 240 circuit in breakers not tied together? How do you handle that in a fuse box? Link to comment Share on other sites More sharing options...

John Dirks Jr Posted July 27, 2007 Report Share Posted July 27, 2007 I think a ground wire is more secure when it is properly attached to a grounding bus bar. Gotta draw a line somewhere right? Link to comment Share on other sites More sharing options...

How do you handle that in a fuse box? You have separate fuses. Generally in the age of fuses there was no such thing as simultaneous trips. - Jim Katen, Oregon Link to comment Share on other sites More sharing options...

That's a no-no. - Jim Katen, Oregon Why is it a no-no? What would an implication be? Well, for starters it violates 250.8: 250.8 Connection of Grounding and Bonding Equipment. Grounding conductors and bonding jumpers shall be connected by exothermic welding, listed pressure connectors, listed clamps, or other listed means. Connection devices or fittings that depend solely on solder shall not be used. Sheet metal screws shall not be used to connect grounding conductors or connection devices to enclosures. An implication might be that you'd get a lousy grounding connection. If that screw is one of the panel mounting screws, another implication might be that, in order to loosen that grounding connection, you've got to loosen the mounting screw. - Jim Katen, Oregon Link to comment Share on other sites More sharing options...

Sure, but those aren't them. You asked me to point out defects in the picture. The moment that someone put a 20-amp fuse on that 14-gauge-wire circuit, it required a safety fuse. Since that's not a safety fuse, it's a defect. - Jim Katen, Oregon Link to comment Share on other sites More sharing options...

homnspector Posted July 28, 2007 Report Share Posted July 28, 2007 Elwood556, I think what you are asking is "what is a safety fuse". An s fuse has a smaller base. There is a non-removable adapter (screws in, but not out) that should be installed in the fuse socket so you can ONLY screw in a 15 amp safety fuse for that circuit. Jim will correct me if I am wrong, but I don't think there is a safety fuse over 15 amps, as it would defeat the purpose of preventing over-fusing.

Actually, there are 0-15 amp, 16-20 amp and 21-30 amp versions. Each will only work in the matching fuse holder/adapter. The adaptors won't accept regular fuses. - Jim Katen, Oregon Link to comment Share on other sites More sharing options...
