Blackburn TZB655SD58CK21 – Frequently Asked Questions
1) What is the Blackburn TZB655SD58CK21 Z bar used for?
It is an underground electrical bus connector, a Z-bar type bus bar used to tie multiple conductors together at a common point in a below-grade or enclosure connection. Connections are mechanical, made up with hardware rather than crimped or compression tooling, so it can be installed and re-tensioned with hand tools in the field.
2) How many conductors can the Blackburn TZB655SD58CK21 bus bar land?
Six. The part is a 6-position Z bar, so you get six tap points off the one bar. If your job needs more than six landings you will need a larger position count rather than doubling up on a single port.
3) Does the Blackburn TZB655SD58CK21 ship as a kit with mounting hardware?
It is supplied as a kit, which is how Blackburn designates the bar packaged with its 5/8 inch mounting hardware rather than the bare bar. The catalog description is "Z BAR 6 POS 500 STL 5/8 KIT," with 5/8 referring to the mounting stud size.
4) Is the Blackburn TZB655SD58CK21 Z bar steel or copper?
Steel, per the STL designation in the part description. Steel Z bars are typically used as the structural support and mounting bar in underground and pad-mount connection kits. If your specification calls for a tin-plated copper or aluminum bus for the current path itself, this steel kit is not the right substitution.
5) Is the Blackburn TZB655SD58CK21 made in the USA for Buy American jobs?
Country of origin is the United States, which matters on federally funded utility and municipal work where domestic sourcing is a condition of the contract. Order under manufacturer part number TZB655SD58CK21.
6) Do I need special crimping tools to install this Blackburn Z bar connector?
No. The connection type is mechanical, so conductors are landed and torqued with standard hand tools. No hydraulic crimper, die set, or compression tooling is required, which is why these bars are common for underground vault and handhole work where tooling access is limited.
7) How is the Blackburn TZB655SD58CK21 sold, individually or in a multi-pack?
Each. The selling unit is one kit per order line, not a carton or contractor pack, so quantity on a purchase order equals the number of Z bar kits you receive.
