Re: circuit breaker panels
Don,
Looks like our choice of words was kinda similar.
Gunny,
Although it is certainly not a bad idea to use a larger panel for future expansion. In fact, you may be doing someone a huge favor someday.

Re: circuit breaker panels
If I remember correctly prior to 96 change didn`t there have to be 2 spaces left in a panel at a final ?I know now we can max a panel out but I`m sure that there was something to that effect.

Re: circuit breaker panels
On a related tangent, the panel in my own house has two empty spaces at the bottom, but this is because behind those empty, numbered spaces there is nothing to connect a breaker to! Why would the manufacturer (Square-D) put knockouts in the panel if there's nothing behind them?
As a result, I now open up panels to make sure I get an accurate count of how many spaces there are for new circuits.

Re: circuit breaker panels
I've seen that on Siemens temps too. I think there's probably a busbar with more spaces for a higher price (interchangeability), with a faceplate to match both. Just a guess.

Re: circuit breaker panels
Manufacturers are trying to save 2 cents on every panel just like residential contractors do. Reuse an existing cover and box design (fewer parts to inventory) and don't give any more busbar then the customer is willing to pay for.
This is very common on panels with less than 20 circuits and has been standard practice for the 25 years I've been in the industry.

THAT WAS QUOTE FROM JIM DUNGER.
I have only one question as a Residential Contractor......Where do you sleep?
I have had this discussion a thousand times and my reply is always:
1)Where does your family sleep?
2)how many malls,refineries,stores and other commercial buildings burn down because of poor electrical work?
I personaly take my job and career VERY SERIOUSLY and would NEVER change the ways i have done things thru the years!

Re: circuit breaker panels
I think you took that the wrong way. I believe he was speaking for the panel manufacturing company, along production lines. Fewer changes in production standards result in more profit.
I've never heard of someone salvaging panel pieces in the field.
