Power accessories turn individual components into safe, working systems. Solar and DC accessories include PV cables, connectors and branch connectors, battery cables, lugs and terminals, fuses, DC breakers and disconnects, bus bars, shunts and battery monitors. AC accessories include heavy-duty extension cords, generator cords, surge protectors, power strips, plug adapters and outlet testers.
Correct ratings matter more than anything else. Cables must be sized for the current and length to avoid overheating and voltage drop. Fuses and breakers must be rated for the voltage and current, and for DC use where needed. Connectors should be compatible with each other, and outdoor items should have suitable weather ratings.
Undersized or uncertified accessories are a common cause of electrical fires. Choose parts with recognized safety certifications, follow manufacturer guidance and local rules, and have permanent wiring done by qualified electricians.
Buying power accessories
- Size cables using current and run length, and check voltage drop for low-voltage DC systems.
- Use fuses and breakers rated for DC where the circuit is DC, and at the correct voltage and amperage.
- Check connector compatibility, as similar-looking connectors may not mate safely.
- Choose extension and generator cords with the right gauge and outdoor rating.
- Look for safety certifications on surge protectors, cords and breakers.
Questions about power accessories
What cable size do I need?
It depends on current, run length and acceptable voltage drop. Use a cable sizing chart from the component manufacturer or ask the seller.
Can I use AC breakers in a DC system?
Not unless they are rated for DC. DC arcs are harder to interrupt, so use DC-rated protection.
Do surge protectors wear out?
Many surge protectors degrade after absorbing surges. Look for indicator lights and replace them according to the manufacturer's guidance.
