A hand cart for dispensing wire is provided. The hand cart comprises a cart body extending vertically between a bottom portion and a top portion, and a plurality of wheels connected to the bottom portion of the cart body. The hand cart may support multiple racks, each rack having bins to house wire containers. The racks may have a dispensing cone for directing wire as it is pulled out of the wire containers. The cart is equipped with a brake assembly connected to the bottom portion of the cart body, the brake assembly having an engaged configuration in which the assembly extends to a surface on which the wheels rest and engages the surface to prevent the hand cart from changing location, but allowing it to be pivoted about the brake assembly.
