Re this thread here: http://www.talk.electricianforum.co.uk/television-satellite-forum-tv-aerials-digital-freeview-satallite-cable-f-type-plugs-h/13974-bonding-digital-aerial.html#post278676
Sorry for digging up an oldish thread, but i'm really confused about the bonding issue of a home distribution amp. Several professional aerial installers websites show pictures of their 'head-ends' showing bonding green and yellow going into adaptable boxes. Does this mean they're just bonding to the supply?
I've just installed a Labgear HDU681 which has a '6mm bonding point' on it. The combi boiler is in the loft as well as as the amp so there are several options for earthing the aerial system!
Option 1 - Bond it to the supply 13A socket earth terminal (on a 32A ring main with 2.5mm TnE cables)
Option 2 - Run a 4mm to the MET. Which seems to be the required but not necessarily most sensible option!
Option 3 - Bond it to the central heating pipework. (Which already has a nice set of unneccesary clamps and green'n'yellow!)
Hayulp!
PS I spotted the part about Class II equipment could have a touch current present on exposed metalwork'. Is that the mistake you meant?!
PPS Found this info:
Loft Box Labgear HDU681S information
In the notes section they state 'use 6mm cable to provide protective earth bonding'. They don't state where to bond to though!
