fit cont. bond, loosen meter tails, remove outlet side, swing meter out fit blank cap an retighten both ends, technically the correct way is to remove the meter to a safe place and fit dust caps, cap the supply and fit those internal red caps into the meter tail nuts, however i asked a CORGI inspector years ago did he want me to remove completely or swing it out as i normally do, he said technically you shouldnt support the meter on one side only in case it pulls the bracket off the wall, to which i answered i would check how secure the bracket was first and if loose i would fix it properly, he said 10/10 for answer get on with it
