ElectricalOM 18th Edition Ready!

 Thursday, October 4, 2018


We are continuously developing our software in order to comply with the new industry requirements and we are excited to announce that our leading Electrical Design and Certification Sofware is now fully compliant with BS7671:2018 - 18th Edition.

ElectricalOM will continue supporting 17th Edition so users can open projects carried out before the 18th edition and automatically convert them to comply with the new standard.

A BS7671 - 18th edition option is now added in the Regulation option and this must be selected in order to start carrying out studies using the new Regulation.
