How load distribution works
The planner treats each entered single-phase load as a quantity that must be assigned to exactly one phase. To reduce imbalance, larger loads are allocated first to the currently lightest eligible phase. A phase limit is used as a planning constraint, so the recommendation can expose cases where the requested loads cannot all fit inside the entered limits.
Why larger loads are assigned first
Large loads have a greater effect on the eventual phase spread. Allocating them early makes it less likely that a later large load will force an already-heavy phase even higher.
What the result means
The phase cards show total allocated load and the percentage of the entered planning limit. The spread between the highest and lowest phase totals is the main imbalance indicator used by this simple planning model.
Worked scenario
With three phases and loads of 8, 7, 6, 5 and 4 units, the planner attempts to distribute the largest loads first and repeatedly selects the lightest eligible phase. The resulting totals may differ slightly depending on the sequence, but the goal is to keep the phase totals close while respecting the configured limit.
Important engineering limitation
This is not a substitute for a full design calculation. It does not model voltage, current, conductor impedance, neutral current, power factor, harmonics, phase-to-phase loads or equipment-specific restrictions. Use the tool for allocation planning and then verify the actual installation.
Frequently asked questions
Can I use watts or amps?
You can use any consistent load unit if every entry uses the same basis. Do not mix watts and amps in the same calculation.
Does the tool account for three-phase loads?
No. This page is specifically for allocating entered single-phase loads.
What if no phase can accept the next load?
The result flags the unassigned load and recommends revisiting the phase limit or the overall load plan.
