Busbars & Power Distribution
DC busbars, fuse blocks, and terminal strips for 12 V, 24 V, and 48 V systems — vans, RVs, boats, off-grid solar, telecom and battery cabinets. Tin-plated copper bus on flame-retardant bases; PowerBar-class 600 A bars with 3/8"-16 studs down to 150 A common bars with M8/M6 studs; ATO/ATC, MIDI/MEGA/ANL, Mini ANL, and MRBF fuse blocks; 25–30 A barrier terminal strips. Stocked; same-day shipping by 2PM ET; Net-30 for trade accounts.
Choosing: size the busbar by total continuous current with all terminals landed and match the stud to the lug (3/8" for 4/0–500 kcmil, M8 for 2–4/0, M6 for 8–2 AWG). No more than four terminals per stud (ABYC E-11.10.4). Every positive feed needs a fuse within 7 in of its source; the fuse family must match the system voltage — ATO, MIDI, MEGA, ANL are 32 V; MRBF is 58 V; Class T is 125 V — and its interrupt rating must exceed the bank's short-circuit current (lithium banks need MRBF or Class T at the battery).
