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 Software 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.
