Seems to me, it would be a change in polarity not a change in phase. A change in phase is a change in timing, like in three phase systems.
Dedicated Circuits - Subpanel importance?
My system is no more. Sold everything. Starting from scratch. Thanks to you and seven months of experience I am doing the following, which is taking care of the number one component, the room:
- Treating. The full GIK order in October is starting to arrive.
- Running one or more dedicated circuits.
I am addressing #2 in this post. There are extensive discussions here and one can spend hours if not days trying to wring-out the critical details needed for a DIY solution. I have spent hours and there a few things I need to confirm before I proceed because I was unable to find definitive answers.
I am doing this myself. I do not want or need lectures on only having a licensed electrician do this work. I have been doing my own electrical work for many years and am very comfortable doing so.
- Does a subpanel help? Is it required? Subpanels are typically supplied from a breaker off of the main panel's bus, so I'm guessing there is no advantage in terms of SQ? Perhaps if I can independently ground the subpanel it might make a difference?
- Opening up my walls is not an option, so I need to use conduit. This may restrict the number of lines if the wire should not share the same conduit? If I am restricted to Romex 8 or 10,2 versus metal-clad, is it okay for two runs to occupy the same conduit?
- How much better is metal-clad? Is it required vs Romex? Will metal conduit accomplish the same result with Romex?
Answers to these questions will complete my plans and I will go forward at speed. Hopefully this discussion helps others as well even if it's to know what to have their electrician setup for them.
Thank you!
