 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.
