Panel capacity rough checker
Use conservative service and major-load assumptions to decide whether an electrician should review load management or panel work early.
Planning estimate only
This is a planning estimate, not an electrical approval. A licensed electrician or local authority must confirm service capacity, code requirements, permits, and final installation design.
Inputs and assumptions
- This is a planning estimate, not an electrical approval. A licensed electrician or local authority must confirm service capacity, code requirements, permits, and final installation design.
- This rough checker uses conservative major-load assumptions and does not replace a load calculation.
Good questions to ask
- What would you need to confirm before choosing the circuit size?
- Would load management avoid larger panel work here?
- Which large home loads affect the final design?
