Please read before relying on any calculator results for real-world electrical work.
ElectroCalc's calculators are provided for educational purposes, quick estimates, and general reference. They are built using standard formulas and publicly available engineering data (such as standard AWG resistance tables and Ohm's Law relationships), but they are not a substitute for professional engineering judgment, certified electrical design, or compliance verification.
Calculators like Wire Gauge / Voltage Drop touch on electrical safety directly. A few important limitations to understand:
For any installation involving mains voltage, building wiring, or anything where an error could cause fire, shock, or equipment damage, consult a licensed electrician or professional engineer and verify against your local electrical code and manufacturer datasheets.
ElectroCalc is provided "as is" without warranty of any kind, express or implied. While we aim for accuracy and use standard, well-established formulas, we do not guarantee that results are error-free, complete, or suitable for any particular purpose. Calculations depend entirely on the values you enter — incorrect inputs will produce incorrect results.
To the fullest extent permitted by law, ElectroCalc and its creator are not liable for any direct, indirect, incidental, or consequential damages arising from the use of, or inability to use, these calculators — including but not limited to equipment damage, injury, fire, or financial loss. Use of this site and its tools is entirely at your own risk.
Resistor color code, capacitor code, and similar decoders follow standard industry conventions (e.g. 4-band and 5-band resistor color codes, EIA capacitor marking systems). Manufacturer-specific or non-standard markings may not be accurately represented. Always cross-check critical component values against the manufacturer's datasheet.
If you notice a calculation that appears incorrect, or have questions about how a specific calculator works, reach out via the Contact page — we take accuracy seriously and want to fix genuine errors quickly.
