Use the usual project channel for calculator corrections, tool suggestions or partnership enquiries. Do not send emergency electrical safety issues through this site.
If a tool result points to a possible overload, RCD issue, damaged lead, hot plug or protective-device concern, stop and escalate it on site rather than waiting for a website reply.
For content corrections, include the tool name, the input values used and what looked wrong, so the issue can be checked properly.
