North American Standards for Industrial Control Panels

That looks like it would be a blast to wire! I'd make it a little less messy, but still looks fun!

Nice video. Thank you for taking the time to create this!

good job i encourage you

Where is the requirement for all components in a branch circuit motor starter to be made from the same manufacturer stated? As well, where can you access a list which contains the approved all combination starter circuits which are approved to UL508?

[@ianharwood7425]

Good question. The quick response is that this is NOT a requirement. The point I was making is that manufacturers wanting to sell into the USA must have UL listed combinations. Manufacturers could choose to collaborate and pay to have a mixed combination tested and listed - but this is very unlikely.

Could you give examples on how a breaker is installed in breaker slot on a breaker panel bus bar?

[@nbehpour4395]

Is it a code requirement to have q main disconnect switch and when does it have to be a fused disconnect?

[@MR-vc1yi]

Hi, on that panel layout, i can see 2 Disconnects. I believed the top most is the Main Disconnect, what is the other Disconnect is for?

[@ianharwood7425]

That is a good question. This panel is purely for demonstration purposes. We wanted to show both options as Switch Fuses are trusted, and therefore very common in the USA market.

can u won see fuse board instalation

Does cUL508a comply with the CSA standard?

[@ianharwood7425]

Canada has its own standards which strongly reflect those used in the USA. Canadian customers are normally happy to accept UL marked products/assemblies, BUT PLEASE ASK.

NOT a good place to have the braided door bond, otherwise a very nice looking panel.

At 5:30 you note a previous video relating to Miniature Circuit Breakers.. are you able to provide a link to that video.. I searched, but could not spot it. Thanks.

[@ianharwood7425]

Hi. Below is the link to the first video on this topic. It isn't particularly about the use of miniature circuit breakers (they get a mention) but is more of a general overview.kzbin.info/www/bejne/jIqliJyVa7N5aZqIhe standard MCB we are so familiar with in Europe is normally assessed against the standard EN 60947-2 if it is being used in an industrial environment. For the North American market, these MCBs are known as supplementary protectors and comply with the US standard UL1077. As such, their use in industrial control assemblies is limited to well defined applications, normally in the control circuit only. Circuit breakers being used in a "branch circuit" (essentially, one supplying a load) must comply with UL489, which the standard European MCB normally will not.Further information can be found in this publication: literature.rockwellautomation.com/idc/groups/literature/documents/sg/1492-sg122_-en-p.pdf

Does UL have wire color code and where is it written
