Consumer Unit Selection Guide:

Step 1. Determine the type of consumer unit configuration required: i.e: split load, dual tariff, standard or combination of split load / dual tariff. For each switch disconnector or RCD to be used allow 2 modular.
Step 2. Determine the number of outgoing circuits required. i.e: Cooker, Lighting, Ring Main, etc For each circuit to be protected by an MCB or RCBO allow 1 modular way.
Step 3. Determine what control products are required. i.e: Bell Transformer, Time Delay Switch, Contactors etc
Step 4: Determine the number of 'spare' modular ways required for future upgrades. For each 'spare' modular way select 1 sentry blank module (5544s - available on this website)
Step 5: Now add together the total number of modular ways required.
Step 6: Select from the MK Sentry range of Insulated (plastic), metal, flush or stacked consumer units.
