Use MCA and max breaker from the mini split label to estimate breaker size, poles, copper wire size, and voltage drop.

Find the largest standard AC breaker allowed from nameplate MOCP, or estimate from compressor amps when the label is missing.

Estimate home EV charger installation cost, credits, rebates, panel work, permits, and net cost from your own quote items.

Choose the smallest EV home charger amp setting and breaker size for your daily miles, charging time, car limit, and home voltage.

Choose a copper AWG wire size for LED strip feeds by voltage drop, load, wire length, feeds, and optional checked wire.

Plan LED strip feed points, injection spacing, current per feed, power supply watts, and feed wire voltage drop.

Plan a centered recessed-light grid with fixture count, spacing, wall offsets, and an optional brightness check.

Estimate capacitor RMS ripple current, rating headroom, needed parallel capacitors, and ESR heat for common circuit cases.

Calculate L-pad series and parallel resistors, actual dB cut, amp load, and resistor heat for speaker pads.

Calculate total speaker load in ohms for series, parallel, or series-parallel wiring, with amp safety and power split checks.
