Bug reports, data corrections, and general questions — all welcome.

What's most useful to include

• Bug reports: which calculator, which code tab (PEC/AS-NZS/NEC), the exact inputs you used, and what result you got versus what you expected.
• Data corrections: the specific value you believe is wrong, and if possible, the correct value with its source (standard, edition, table/clause number).
• Feature requests: which calculator or code you'd find useful that isn't covered yet.

OhmWorks is actively maintained — real reports genuinely help improve the reference data over time.
