25 amp max. sticker?? Stupid question but, huh!!
Jim Port replied to Stephen Lagueux's topic in Electrical Forum
John was correct. There is a 125 amp bus stab rating. Since 100 is already accounted for the maximum is a 25 amp on the same tabs. Very common and not a mistake. The label inside the panel will have all this information on it. -
Not an NEC issue.
-
The sink can be right next to the panel. as Robert said there are workspace requirements that need to be met.
-
All the ports are connected together. They make one common connection.
-
Those are push in wire connectors. Ideal and Wago make them. They serve the same purpose as twist on wire nuts. The splice needs to be in a box with a cover.
-
The yellow symbol is used when laser light is involved. This would be typical in a FIOS system or another high speed network.
-
I would guess it had something to do with something like a fiber optic. Perhaps for phone or internet service.
-
I can't read the embossed labels, but all the conductors on that side look like #12's.
-
The second and third breaker down are the style that accept 2 conductors.
-
The #12s on a 30 amp breaker could be correct if the load was an air conditioner or a motor load.
-
CH did not have the same retention clamp as Square D. I just looked on the truck and the newer CH breakers with the plastic mounting foot are labeled for 2 copper conductors or 1 aluminum. I did not see a label on the older metal foot style. The clamp is a slightly v-shaped lug with a flat pressure plate.
-
Those look like Cutler-Hammer CH breakers. The panel cover would have been tan if it had not been painted over. CH does hve some breaker listed for 2 conductors.

Using the correct terminolgy helps with understanding and properly applying the correct code articles. Otherwise important details can be left out. I would rather show that I know the difference by using the correct terms. On a related note, lack of use of the proper wording lets murderers walk the streets on technicalities. Tell me the wording doesn't make a difference. I understand regional code differences, but that does not mean that the "regional slang" is correct. In your example above the locknut is not being grounded, regardless of what it is connected to. It would be a bond.
-
Thanks for the additional pics. I am guessing the POCO allows the sockets to contain the GEC? I am looking at the 1/2 EMT as protection for this. Is that metal conduit leaving the meter sockets? You correctly identified what you have as a service panel. With that said the bond screw should be installed. That leaves the only issue as the GEC not being properly terminated.
-
Kurt, I am sorry that so few of your tradespeople know the proper terminolgy of their professions or the purpose of what they are installing. Continued mis-application does not help. The NEC also addresses the grounding and bonding differently. Grounding and bonding serve two different purposes.
-
Phelps Dodge was just another manufacturer of cables.
-
First, it would be a bonding locknut, not a grounding locknut. Secondly they are not always required. Thirdly, the bond screw should not be engaged if this was not service equipment. I can't see if the other apartments are fed out of this panel or not. A 100 amp panel typically would not feed multiple apartments. I know the OP stated service, but I question it.
-
There should have been a panel diagram on the label inside the panel showing the bus arrangements.
-
Why do you think the cable needs a clamp where it exits the wall? What type of clamp is listed for that use?
-
Doug, It was typical to see the NM on furring strips, although sometimes I did see it run just on the block. Couple of issues in the pics, one not secured within 12" of the boxes and IMO it does not follow the building surface closely enough due to the lack of being unsecured.
-
Unless someone deemed that cable subject to physical damage it would be compliant if the strap was listed for the use. Like Doug said, I too have never seen a furnace listed for use with flex cord.
-
A panel change typically does not trigger the need for AFCI protection. Nor would it trigger the need for upgrades anywhere else in the house.
-
Under the NEC the WH is considered a continuous load and the breaker needs to be sized for 125% of the load. A 25 or 30 amp breaker is commonly used. The 30 is more common due to easier availability.
-
Not as far as the GFI or surge. Furnaces are not listed for cord and plug connection in my experiences. They are hardwired.
-
The stove is not going to meet the frequent interchange nor the need for a flexible connection to limit vibration. It does not satisfy 400.7. The installation as shown is wrong.
