its never a good idea to go to heavier fuse the potential exists for amp draw to be hig.h enough to damage a component or inaccessable wire
Probably...The 6V 40A relay figures out as 240Watts...The same relay at 12V 30A figures out as 360Watts.
Fuse 104 (40A). Hope this helps! Fuses are detailed and illustrated in the Owners Manual - See "Related Questions" below for more
If you want an American plug to power a 30A 220V device look at a dryer outlet. It will have an extra neutral conductor, but it is standard. Otherwise, you can go with a 220V 30A TwistLok plug. All the home centers [I've been to] carry these plugs. 10ga wire is heavy enough for 30A runs under 75ft, though for a 27A appliance you should consider a 40A breaker with 8ga wire.
if the appliance is manufactured after 1920 it will have a nameplate somewhere near the power connection. this nameplate SHALL have the amperage and voltage required. the fuses in a house are sized so as to not set the house wiring on fire. that being said water heater nameplate 28A 240V can be on for periods longer than 20 minutes (continuous duty) so must derated 10% 31A . minimum standard wire size #8 30A, 35A or 40A fuse no time delay needed. air conditioner 25A 120A LRA 240V minimum standard wire size #10 30A fuse time delay needed.

The Electric Company - 1971 40A 5-40 was released on: USA: 12 December 1975
no because it is an even number but not 2
AWG # 8 copper
10mm2 : 40A
The main fuses protect the feeder lines from the electric company's feed to the main panel for the maximum ampacity rating of the wire. So depending on the size of the incoming tails nothing is gained by reducing the main supplier's cut-out fuse rating to 60A or 40A.
Hopefully this helps I wasn't able to import a pic so I tried to duplicate it the best I could. 1 2 6 7 8 13 3 4 5 9 10 11 12 14 15 1 Dome Light 10A 2 Headlight upper beam 10A 3 Fog Lights 15A 4 Tail Lights 10A 5 Hazard warning flashers 10A 6 Heater Fan 30A 7 Air Conditioning 8 Fuse (+B) 40A...battery 9 Ignition Switch 40A 10 Power Window Control 30A 11 Headlights 30A 12 Engine Control 20A 13 Altenator 80-1 100-2 14 Condenser fan motor 25A 15 Air Conditioning compressor 10A This is for 2.4, 3.0 & 3.5 liter engine models...99 Montero Sport
