What This Standard Covers
- Current transformer sizing and placement for whole-home and circuit-level monitoring
- Sub-meter locations for pool, HVAC, EV charging, and high-load branch circuits
- Communication wiring from energy monitoring hardware to network closet
- Panel space and breaker slot requirements for energy management hardware
- Integration data points for home automation and building management platforms
- Load-shed relay wiring requirements for demand response control
Who It Is For
- Electricians coordinating panel layout with low-voltage energy monitoring hardware
- General contractors managing energy management scope on luxury residential builds
- Architects incorporating energy monitoring infrastructure into electrical drawings
- Homeowners requesting real-time energy visibility and utility cost management
When To Use It
- Before the electrical panel layout is finalized to reserve space for monitoring hardware
- During rough-in to run communication conduit from panels to the network closet
- Before insulation or drywall to verify CT and sensor positions
- At system commissioning to confirm data feeds from all monitored circuits

Field Notes
You cannot manage energy you cannot measure. The infrastructure decisions on this one-pager need to happen when the electrician is still in the panel. Adding CTs and sub-meters after drywall is a significant change order. Adding them at rough-in is a line item.
Energy visibility also feeds automation. When the home automation system knows the pool pump, EV charger, and HVAC are running simultaneously, it can sequence loads to stay below a demand threshold. That capability starts with the pre-wire decisions this document covers.
