What are we speaking about? The subject or the plugs? Or the sockets?. These are three different things .
So I will one by one reply in three different mails to make clear enough. The current reply is related to the septic tanks blowers installation: the needed power cable.
The subject is 70 meters of 5 x 10 mm SQ.MM.
Note that here I am writing 5 x 10 mm. SQ. MM not as per the subject 4 x 5 SQ. MM. Mr. Edwin the site Electrical required this. According to him the cross section is called 5 x 10 mm SQ.MM. not what is written on the insulation 4 x 10 mm. SQ. MM
Please verify. We need the cross section as requirement!
If anything regarding the 70m Cable still not clear; then, please call me or reply to this mail.
