 LOM detection comes in two flavours: **Type A** and **Type B**. LOM detection comes in two flavours: **Type A** and **Type B**.
  
-**Type A** is the strongest form LOM detection, which results ​in the quickest detection time. It requires a low impedance connection to the grid (short, well sized cables). LOM **Type A** will not work with generators.+**Type A** is the strongest form of LOM detection ​resulting ​in the quickest detection time. It requires a low impedance connection to the grid (short, well sized cables). LOM **Type A** will not work with generators.
  
-**Type B** has a more soft approach. Resulting in a slightly longer detection time. Still acceptable in several countries ​(South-Africa, and probably, though ​not tested ​and certified ​yet, also Germany). On generators, and also connection ​with a relatively high impedance mains connection, **Type B** will work better than **Type A**.+**Type B** has a more soft approach ​and a slightly longer detection time. **Type B** has been type tested and approved for most Multi/​gridcode combinations. //(The only combination not tested so-far is MultiPlus/​Quattro i.c.w. UK grid code. However this combination is most likely valid. It has just not been type tested yet.)//\\ 
 +On generators, and also with installations having ​a relatively high impedance mains connection, **Type B** will work better than **Type A**.
  
 For generators on which also **Type B** does not work, see Disabling LOM. For generators on which also **Type B** does not work, see Disabling LOM.
Line 77: Line 78:
 Some, bigger or better quality generators, will be able to work with LOM **Type B**. For other less stable generators it will be required to disable LOM entirely. In that case make the installation such that it is still safe: no simple extensions cords, use enclosed wiring cabinets with warnings on the outside and/or an external ENS. Some, bigger or better quality generators, will be able to work with LOM **Type B**.

 ==== Q4: I use ESS, but have disabled feed-back, is a grid-code still required? ==== ==== Q4: I use ESS, but have disabled feed-back, is a grid-code still required? ====
  
 A: Yes, also in this case LOM is required to make for a safe and also local regulations compliant system. Running ESS with disabled-feed-back is still not the same as using a Multi in its default configuration without ESS.  A: Yes, also in this case LOM is required to make for a safe and also local regulations compliant system.
