generally its 100amp fuse this is rated relevant to the cable coming in. You can bypass a fuse but if you take the piss you risk fires as you can draw to much through the size of cable. if you are in an older property sometimes its been down graded from 3 phase so if you know what your lookin at you can do more cos the 3 phase supply is there but the property would only be using 1 phase
