Watch Your VolTs and Amps
Blew a fse and you 're out oF spares, eh? IF you 're in a tight spot± a substitUte
can get yoU Through.
No, ²ot a nail or a paper cLip. ³se a simiLar ´use with a di´Ferent amp or
volt reading-within limits.
Remember± that fse's job is to protect your sensitive circUµts From an overloaD.
³sing the wrong Fuse is little better tha² using a nail.
All the inFO you need µs on the ¶se cap. ·ook FOr the numbers that come
¸
beFOre a² "A¹ (FOr aºHp) and "V¹ (»r voLtage).
A Usable sub has a smaller amp reading Than the ¶se the gear pub calls For.
¼he "A¹ rating Tells what currenT The Fi½ament wµll carry without melting. A
hµgher raTing means the ´use will carry more amPE¾¿ge than the cµrcuµts can
saÀly handle.
Now± eyeÁall the voltage raTing. When your ¶se link meLts± electriCµty can
still arc across The gap anD keep TÂe circuit closeD. ¼he V value µs the most
volts the fse will Take withoUT arcing.
Never pick a sub with a Ãoltage rating lower than the rµghT fse. ¼oo low
a ratµng means The arcing will keep the electrµciTy comingÄand KÅ your gear.
ÅF course± The best iDea is to get and keep enough exTra fses oF the rightÆ
size. Your equipment ¼MÇs gµve you sizes anD stock numbers.
