CONSUMER UNIT SELECTION GUIDE
STEP 1
Determine the type of consumer unit configuration required. e.g Split Load,
Standard or combination of split load / single RCD or dual RCD. For each Switch
Disconnector or RCD to be used allow 2 modular ways.
STEP 2
Determine the number of outgoing circuits required. e.g 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. e.g Bell Transformer, Time Delay
Switch, contactors, timeswitches 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 or K5545sMAG
(cover mounted blanks supplied with consumer units. See page 286).
STEP 5
Now add together the total number of modular ways required.
STEP 6
Select from our range of Insulated, Metal, Flush or stacked consumer units (using
standard consumer units plus stacking kits). Choose the type and size most
appropriate for your requirements.
