    Bno Supply - Isolator

    Hi, I am quoting the switchgear for a BNO install. I have only worked on MEM (Glasgow) isolators but was looking at the contactum TPN 200amp isolator as another option. I need some advice, if I should stick with the MEM. I will be terminating 95mm in the isolator after the UKPN cutout.
