Price for grounding and neutral connection of distribution boxes

Neutral and grounding terminal blocks for distribution boxes typically range from $5 to $30 per unit, depending on material, size, and configuration.

Typical Options and Prices

Copper Bridge-

Type Terminal BlocksDesigned for secure neutral and grounding connections in distribution boxes. Available in 4, 5, 6, and 8-hole configurations. Pure copper construction ensures high conductivity and durability.

Price: Approximately $10–$25 per block, depending on the number of holes and supplier.

Brass Grounding Strips

Pack of 10 brass earth/neutral strips suitable for PE30 distribution boxes, lighting boxes, and cabinets. High strength, corrosion-resistant, and easy to wire. Price: Around $15–$20 for a pack of 10, making it roughly $1.

50–$2 per strip.

DIN Rail-

Mounted Grounding TerminalsGreen/yellow housing for easy identification, mechanically clamped onto DIN rails. Provides reliable grounding and neutral connections while saving installation time. Price: Typically $5–$15 per terminal, depending on size and current rating.

Factors Affecting Price

Material: Copper blocks are generally more expensive than brass due to higher conductivity. Number of connection points: More holes or pins increase the cost. Mounting type: DIN rail-mounted terminals are convenient but may cost slightly more than simple panel-mounted strips.

Supplier and region: Prices vary by distributor and shipping location.

Recommendation

For small residential projects, DIN rail-mounted copper or brass terminals are cost-effective and easy to install. For industrial applications requiring higher current capacity, pure copper bridge-type blocks are preferred for durability and conductivity. Always check the supplier for exact pricing and availability before purchase.
