Minimum hardware 

• 5x20mm Glass Tube Fuse (Appropriate Amperage Rating): Required  the holder is an empty enclosure and must be populated with a fuse matched to your load's max current draw to function as a circuit protector.
• Wire Cutters / Wire Strippers: Required  to strip the 22 AWG lead ends for crimping, soldering, or inserting into terminal blocks.
• Soldering Iron & Solder OR Wire Crimps: Required  to securely join the inline fuse holder to your main DC/AC power wire rail.

Safety Warnings

• Disconnect Power First: Always ensure your circuit's power supply is completely switched off or disconnected before splicing this fuse holder into the power line.
• Inline Placement: Always install the fuse holder on the POSITIVE (V+ or Live) wire rail, never on the Ground/Neutral line. Isolating the positive supply cuts off power to the downstream circuit during a fault.
• Current & Voltage Limits: Do not exceed the rated limits of the 22 AWG wire (typically recommended for up to 5A continuous current). For higher current applications (>5A–10A continuous), monitor wire temperature under load.

Accessories Included in the Box

• 5× Inline 5x20mm Glass Fuse Holder with pre-attached 22 AWG Lead Wires (Glass fuse not included)

Frequently Asked Questions 

• Is a glass fuse included with this inline fuse holder?
  No, the glass tube fuse is not included. This holder is sold as an empty enclosure so you can insert a 5x20mm glass or ceramic fuse tailored to your circuit's specific current rating.
• What size fuses are compatible with this holder?
  This holder is specifically designed for standard 5mm × 20mm (5x20mm) glass tube or ceramic tube fuses.
• Can I use 6x30mm fuses in this holder?
  No, 6x30mm fuses are physically too long and wide to fit inside this housing.
• Is this fuse holder suitable for AC as well as DC applications?
  Yes, it is rated for both AC and DC low-to-medium power circuits up to 250V.
• What is the maximum voltage rating for this fuse holder?
  The housing and lead wires are rated for up to 250V AC/DC.
  
• What is the maximum recommended current for the 22 AWG wires?
  We recommend a continuous operating current of up to 5A. For short burst loads, it can handle up to 10A, but continuous high current may cause wire heating.
  
• Can I use this fuse holder on a 12V or 24V automotive DC supply?
  Yes, it works exceptionally well for protecting 12V and 24V DC accessory lines in automotive or robotics projects.
• Which wire should I connect the inline fuse holder to?
  Always connect the fuse holder inline with the Positive (V+ or Live) wire, never the Ground (GND or Neutral) line.
  
• Does it matter which red lead wire is input and which is output?
  No, the fuse holder is non-polar and symmetrical; current can flow in either direction.
  
• How do I insert or replace the glass fuse inside?
  Simply push and twist the two halves of the black housing counter-clockwise to unscrew it, insert the 5x20mm fuse, and screw the housing back together.
• Why is my circuit not receiving power after installing the fuse holder?
  Check that a working 5x20mm fuse is installed inside, ensure the housing is screwed tightly together, and check for 0Ω continuity across the assembly.
  
• What happens if the internal spring loses tension?
  The spring maintains contact force against the fuse end-caps; make sure the housing is fully screwed together so the spring remains compressed.
  
• My lead wires are getting warm during operation — what should I do?
  Warm wires indicate your load current is approaching or exceeding the limits of 22 AWG wire. Reduce the load current or switch to a heavier gauge wire holder.
  
• How do I know if the glass fuse inside has blown?
  Visually inspect the glass tube to see if the internal wire filament is broken, or use a multimeter in continuity mode to check across the fuse terminals.
