In the parameters for the load centers I identified the following options:

1.)  Style:  Flush Mount, Surface Mount
2.)  Indoor/Outdoor:  Indoor, Outdoor
3.)  Height:  Distance from floor to bottom of box (in./mm)
4.)  Breaker No.:  6, 8, 12, 24, 30, 40, 42, 54, 60
5.)  Amperage:  100, 200
6.)  Main Lug:  Main Breaker, Main Lug
7.)  Adv. Options:  None Currently

There is no material/color assignment. 

I've created a 6 and 8 breaker box (main lugs only).  I will need to add in additional boxes that only have main lugs and not a main breaker for the other sizes, but that is work for another day.

The inside of these boxes and the breakers are very simple and low poly.  The idea is mostly to convey the number and location of breakers and overall dimensions:

Various load center sizes, view model here:

All load centers are 200 Amp except for the 24 space unit which would be rated for 100 or 125 Amp.

Tomorrow I will finish modeling up some typical load centers (breaker boxes) like the one below (200 Amp, 40 Spaces):



I'm not going to put any special logic into this module yet, just a simply positioning and selection.  However at some point it would be really cool to use the plugin to setup the various breakers and identify circuits as well as assign specific elements to a circuit.

For now three sizes of breaker components are provided and it is up to the user to manually configure their panel if they so choose to do so, otherwise is is more representational than anything else.

When it comes to setting the vertical height of the load center what is the method used to measure from the floor?  Center, Top or Bottom of the panel?

I will provide some common panel sizes (spaces):  24, 30, 40, 42, 54, and 60.

My breakers are based on the SquareD QO series as are my load centers however they are considerably simplified to maintain a low poly count.

Also for now I am only going to provide flush mount and not surface mount however I will probably enable both in the future.

Various combinations of QuickPorts yields a number of possible 2D symbols:



I've tried to stay with conventional symbols as much as possible.  Please let me know what you think on this.

The low voltage module is working pretty good now.  I just need to wrap up the 2D symbols and then we will see if I can put together a few typical load centers, and then its out to the public for some BETA testing.

A 2-gang, 12 port low voltage box is probably your worst case scenario:



Each port can be assigned one of the following:

- CAT6
- CAT5e
- COAX
- PHONE (RJ11)
- RCA (Audio/Video, gold plated)
- BLANK (Plastic Insert)

Additionally each port has its own unique material/color which by default is "White".  The faceplate can also be assigned a unique material/color.

Similar to other outlets the advanced options can be enabled which allows for vertical or horizontal mounting.

The number of possible QuickPorts is limited to the following:

1-Gang:  1, 2, 3, 4, 6
2-Gang:  8, 12

There are additional 2-Gang QuickPort wall plates that I have not added.  I will only add these if requested, since they are already covered by the 1-Gang option.

The updated toolbar:



I will leave it up to inquiring minds to figure out what all these icons mean.

Just loaded the Wall Plugin into SU 2019 and so far all is good. I did notice that the HTML menus seem to be loading quite a bit faster and the performance overall seems to have improved. It looks like the browser engine under the hood has been updated and already there is a marked improvement, thank-you SketchUp.

When you drag a menu and then select a drop down box the bug where the drop down opens up at the previous location is now resolved. Looks like I might have to update to SU 2019.

I've also added in the RCA QuickPort by request.



You will be able to assign a unique QuickPort outlet to each port of the wall plate and also assign it its own unique color if you choose (this will be important for people who are color coding network jacks).

The low voltage components that will be utilized in the Medeek Electrical extension:

This collection is only the QuickPort components there is also the QuickPlate and Decora styles that I have not gotten to yet.

For low voltage I am going to start with only one style for now and that is the Leviton Quickport system:



The advantage with this system in my opinion is that there will be less electrical boxes to install since you can get more than one outlet per box (max. is 6 ports for a single gang box).

My only problem now is how to show this type of port on the electrical plan.  Typically I would have a symbol for TV, Phone and/or Data.  However, what does one show when you have a situation like above where all three data types are compressed into one box.  Even worse, what if I have the 6 port version and have one phone jack, two CAT6 jacks, two coax jacks and a blank?

What is the preferred convention?  If there is one.

Additionally there is the 2-gang low voltage box (Carlon SC200AR) which can be fitted with a Quickport face plate and have a maximum of 12 separate ports, yikes.

I will provide the same 14-xx outlet in 30 and 50 amp without the dryer or range designation, for those applications that are something other than those two typical residential usages.

I was looking at Square D service panels (load centers) last night and I'm most familiar with their QO product, not a huge fan of the cheaper Homelite product line.  I can't seem to find any decent drawings or dimensions for these enclosures other than the overall size.  If anyone can direct me to a resource which will allow me to model these up with some accuracy I would like to add in a handful of service panels.

I'm probably not going to dive too deeply into the load center module right now, only providing a basic model and label, but eventually it would be nice if one could assign specific outlets, switch and light fixtures to a given circuit/circuit breaker.  There is a lot that can be done with this sort of thing.

A few more options for the switches module:



One of my favorite switches, the Trimatron.

I've added in the option for 240V receptacles:



These are limited to single gang configurations as shown (2 gang electrical box).  They can be mounted either vertical or horizontal.  The annotation allows one to specify either a dryer (D) or range (R) outlet. 

By default the color of the outlets is a dark brown (thermoplastic) but can be modified by the user as well as the wall plate material.

I was going to add in an option for a welder outlet but I'm not sure which outlet type is the most common for this application, it appear that the NEMA 6-50 is commonly used for welders but until I get more information or a direct request for this particular NEMA receptacle I will leave this one for now.

Dimensions for these outlets types are per Leviton's product lineup, as is the wall plate.  For now I've employed the standard 2-gang Carlon PVC box but for a heavier circuit like these I personally would probably go with a metal box and the appropriate mud ring and cable clamps.

Option for weatherproof GFCI added:



I haven't gotten every combination but I think I now have about 85% of the most commonly used configurations added in for outlets.  I will now return to the switch module and work that over for a while until it is also about 85-90% coverage.

I also still need to add in a completely new style: 240V

This will comprise single gang outlets for clothes dryers, welders, and ranges.
