Joules - surge protector question
I see surge protectors with differing values for joules.... but it doesn't say what is better ... is higher better than lower values ? thanks

Spike protectors are voltage specific. Two sets of MOVs, 2-sets of TVS 2 sets of gas gischarge tubes. L1 and L2 to L0. L1 and L2 to earth on a 240 volt suppressor. On a GOOD setup each component has a fuse. Device taken off line and a continuity check confirms if fuses have been faulted. Multiple discrete components protected by a single fuse is idiocy.
