Practical limits

Ask about a load check.

If a calculation, page or label is confusing, say what you entered and what did not make sense. If equipment is overheating, damaged, wet or repeatedly tripping a breaker, stop using it and contact a competent electrician or emergency service where needed.

Something looks unclear

Tell us which page you were on, what you entered, and which result or warning did not make sense.

Do not wait for a reply

If there is heat damage, smoke, water near electrics, burning smell or repeated tripping, stop using the equipment and get local help.
