For corrections, tool suggestions or partnership enquiries, contact the site operator through the usual project channel. Do not send emergency electrical safety issues through this site.
These tools are deliberately written for planning conversations between electricians, site managers, facilities teams and hire/specification desks. They are not certification tools.
Where a result involves protective devices, cable ratings, RCDs, live equipment or suspected overheating, stop and involve a qualified competent person.
