Fused Main Switch and Earth

Former Community Member
Former Community Member
Hi
My meter tails have a 2 pole 80A HRC fused switch which feeds the CU.
The earth from the MET is also connected to the switch, I have seen a few others were the earth bypasses the switch and go’s straight to the CU. Does this cause a problem?
Also the property is a TN-S and all the main bonding (Gas and water) are connected to the CU as there is only one terminal at the MET?

    Depends on the method of shock protection used by the switchfuse - if it's Class I it should certainly be earthed (as a general rule, if it's got a metallic enclosure it's likely to be Class I, although there are exceptions), if it's Class II (double or reinforced insulation) - as would often be the situation with plastic cased devices - then it's usually safe without an Earth.
