A dual EV charging post for a business depot near Baldock.
Two myenergi Zappi chargers on one post, with load management so the site never draws more than 80A. Surveyed, installed and commissioned in a day.
A construction business's depot near Baldock needed two EV charge points to satisfy a planning condition. Ducts had already been laid to the car park, so the brief was one dual charging post on the second duct run, fed from the existing site-office board, with load management so total demand never exceeds 80A.

What we found
- Site survey on 28 Sep 2026: 3 x 100A three-phase intake in a separate intake room, with the site-office supply split off one phase via Henley blocks
- Site office fed by 3 x 35mm supply cable to a Hager single-phase distribution board with double-stacked SPD
- Eight ducted charger positions already in the car park, c.2m apart; c.18m to the furthest duct plus c.8m into the building
What we did
- Installed one myenergi dual charging post carrying two multiphase myenergi Zappi chargers
- Fed the post from two new single-phase circuits on the existing Hager board, each on a Hager 32A Type B RCBO (ADB932R)
- Ran the supply cables through new ducting from the manhole to the post
- Levelled and shimmed the post on its concrete base
- Fitted a 100A fuse in the switch-fuse isolator feeding the office
- Hard-wired both chargers to the network switch in the distribution cabinet (more reliable than Wi-Fi given the building construction)
- Terminated CT clamps in the cabinet and set up load management; set charger 1 as master and charger 2 as slave, CT config and supply-grid limits set
- Updated firmware, confirmed internet connection on both units
- Tested the circuits, labelled the chargers, circuits and junction box, and fitted EV charging bay signs for both bays
- Left the manuals with the site manager
Equipment used
- myenergi Zappi (multiphase) x2
- myenergi dual charging post
- Hager ADB932R 32A Type B RCBO x2
