Estimate only; a licensed electrician and your local authority having jurisdiction decide; not an engineering stamp.

• CanMyPanel gives educational estimates based on our reading of published NEC methods and the values you enter. Results can be wrong because of incorrect inputs, local amendments, edition differences or our errors.
• Do not use results as the sole basis for electrical work. Hire a licensed electrician, pull the required permits and follow your AHJ.
• Do not open your electrical panel. Contact with energized parts can kill.
• The service is provided "as is", without warranties, and to the extent permitted by law we are not liable for damages arising from its use.
